─ Inputs are optically isolated solid state and switch selectable as either active or passive
─ Output relays provide one normally open contact per relay
Ethernet Port
One 10/100 Ethernet port with automatic link polarity detection and correction.
1.11 COM2 Serial Port
This optional port provides RS-232 and RS-485 communication at rates from 300 to 115.2k baud. The port is bidirectional and can be configured for various functions such as demand output, continuous output, extended continuous output, SICS host communications or ASCII command input (C, T, P, Z).
The COM2 port is galvanically isolated for both RS-232 and RS-485, to provide surge voltage protection.
The RS-485 connection can be used as an RS-422 transmit only when sending continuous output to a scoreboard or remote display.
1.11.1 Discrete I/O
The discrete I/O interface option provides dry-contact relay outputs. The relay contacts will switch up to 30 volts DC or 250 volts AC at 1A.
The inputs are switch selectable as either active (for simple pushbutton control) or passive (for connection to devices that supply their own power for the inputs).
1.11.2 USB
The USB port provided is a hardware bridge acting as a virtual COM port, and is used for conversion of serial data.
The port is bidirectional and can be configured for various functions such as demand output, continuous output, extended continuous output, SICS host communications or ASCII command input (C, T, P, Z).
1.11.3 Ethernet
The T72XW Ethernet option provides an RJ45 jack for connection to an Ethernet network or host device. A TCP socket connection can be made to port 1701 to transfer files or to exchange data with a PC. This port can also operate as a print client to send data to a network printer.
EN 6 7000 SERIES INDICATORS
1.11.4 SD Memory Option
An optional SD Memory card provides a medium on which to store files such as Alibi memory, IDs in the counting application and target weights in the checkweighing application.
Note: The SD card is required for alibi memory.
The SD memory can also be used to extract and save the configuration and calibration settings of the terminal.
These can then be restored to the terminal or loaded to a different terminal. This feature can be used to clone the setup of one terminal then transfer it to other units, which minimizes the chance of error in setting up a new configuration.

2.3.9 Setup Access
EN 21
The last icon displayed in the OPERATOR menu accesses the SETUP menu, from which all the terminal’s programming parameters can be viewed and modified. The settings and options available in setup are described in detail in Chapter 3, Configuration: Terminal.
It is not intended that operators enter the setup mode. After a weighing system is installed and is operational, it should not be necessary for an operator to access setup.
Note that a security password can be enabled in setup. When a password is set, it must be entered in order to access setup. This protects the setup parameters from inadvertent changes.
2.4 Basic Functionality
This section provides information about T72XW basic functionality. Functions addressed in this section include:
Zero Clearing Tare Information Recall
Tare Print Target
Refer to Chapter 3, Configuration: Terminal, for further information about programming all the functionality described in this section.
2.4.1 Zero
The Zero function is used to set or reset the initial zero reference point of the terminal. There are three types of zero setting modes:
Automatic Zero Maintenance
Power Up Zero
Pushbutton Zero
When the scale platform or weighbridge is empty, the terminal should indicate zero. The gross zero reference is recorded during calibration. If pushbutton zero is enabled in configuration and the weight is within the zero range pressing ZERO will capture a new gross zero reference point.
Automatic Zero Maintenance
Automatic Zero Maintenance (AZM) enables the T72XW to compensate for the build up of small amounts of weight and track itself back to the center of zero. Within the AZM operating range (selectable from 0.5, 1, 3 or 10 divisions), when the terminal is in a no motion condition, it makes small adjustments to the current zero reading to drive the weight reading toward the true center-of-zero. When the weight is outside of the programmed AZM range, this feature is not functional.
Power Up Zero
Power-Up Zero enables the T72XW terminal to capture a new zero reference point after power is applied. If there is motion during a power-up zero capture function, the terminal will continue to check for a no-motion condition until zero is captured.
Power-up zero can be disabled or enabled, and a range above and below calibrated zero can be configured. The range is programmable from 0% to 100% of capacity and can include a positive range and also a range below calibrated zero.
Pushbutton Zero
.
The pushbutton (semi-automatic) zero function can be accomplished by pressing the ZERO key programming a discrete input or by issuing a serial command.
, by
The range for all types of semi-automatic zero is selectable (Disabled, 2% or 20%) plus or minus from the calibrated zero point.
Remote initiation of the semi-automatic Zero command is possibl e via a discrete input, or an ASCII ‘Z’ command sent serially (CPTZ and SICS interface modes)
EN 22
2.4.2 Tare
7000 SERIES INDICATORS
Tare is the weight of an empty container. A tare value subtracts from the gross weight measurement, providing the computation of the net weight (material without the container). The tare function can also be used to track the net amount of material being added to or removed from a vessel or container. In this second case, the weight of the material in the container is included with the tare weight of the container and the display then reflects the net amount being added to or removed from the vessel.
Tare operations in the T72XW include:
Pushbutton Tare
Keyboard (Preset) Tare
Tare Clear
─
Manual Clear
─
Auto Clear
Pushbutton Tare
Automatic Tare
Net Sign Correction
Pushbutton tare can be configured in setup as enabled or disabled. When disabled, pressing the TARE key has no effect.
If pushbutton tare is enabled, pressing the pushbutton TARE key initiates a semi-automatic tare. The
T72XW will attempt to perform a tare process. If the process is successful, the display changes to a zero net weight indication and the previous weight on the scale is stored as the tare value. The net mode will be indicated on the display.
Several conditions could inhibit the pushbutton tare function:
Motion
– Pushbutton tare cannot be taken when the scale is in motion. If motion is detected when a pushbutton tare command is received, the T72XW will wait for a programmed amount of time (the default value is 3 seconds) for a no-motion condition. If a stable (no motion) weight condition occurs before the timeout expires, the pushbutton tare command is executed.
If there is still motion at the end of the timeout, the command is aborted.
Pushbutton Tare Disabled
– If pushbutton tare is configured as disabled, the TARE scale function key will not initiate a semi-automatic tare.
Negative Gross Weight
– Any pushbutton tare attempted when the gross weight is at or below zero is ignored.
Ensure that the gross weight is above zero.
Keyboard Tare
A keyboard (preset) tare is a numeric tare that is entered manually through the numeric keypad or received serially from a peripheral. The preset tare value cannot exceed the capacity of the scale. Data entered is interpreted to have the same units as the current displayed value. Motion does not affect the entry of preset tare values.
Keyboard tare can be configured in setup as enabled or disabled. When disabled, the numeric keypad and the
TARE scale function key cannot be used to obtain a tare.
To enter a preset tare value manually, use the numeric keypad to enter the tare value (the data entered will display in the weight legend if keyboard tare is enabled in setup at Scale > Tare > Types) and press the TARE scale function key .
If configured in setup, remote equipment can enter a preset tare value using a serial command
If the preset tare is successful, the display changes to a net weight indication.
7000 SERIES INDICATORS EN 23
Several conditions could inhibit the preset tare function:
Keyboard Tare Disabled
– If keyboard tare is configured in setup as disabled, the numeric keypad and the
TARE scale function key cannot be used to obtain a tare.
Over-Capacity or Under-Zero Conditions
– Preset tare is not allowed when the weight display indicates over capacity or under zero conditions. Any preset tare attempted when the scale is over capacity is ignored and a
“Tare Failed–Over Cap” error displays. Any preset tare attempted when the weight display indicates an under zero condition is ignored and a “Tare Failed–Too Small” error displays.
A preset tare can be entered in free format. If the entered value does not match the displayed weight decimal point location or display interval, the entered tare value is rounded to the nearest display interval and the decimal point adjusted to match the gross weight. The rounding method is that 0.5 or more of a display interval (d) is increased to the next display interval and 0.49 or less of a display interval is decreased to the next lower display interval.
When entering a preset tare value less than 1.0, the operator can enter the data without the leading zero (left of the decimal point), but all subsequent display, storage, or printing of this value will include the leading zero. For example, a preset tare entry of .05 will display as 0.05.
If a preset tare has already been established and another preset tare is entered, the second preset tare replaces the previous value (it does not add to the previous value). The replacement tare can be larger or smaller than the original tare value.
Net Sign Correction
Net sign correction enables the terminal to be used for both shipping (inbound empty) and receiving (inbound loaded) operations. Net sign correction can be either disabled or enabled on the T72XW.
If net sign correction is disabled in setup, the stored weight value in the tare register is assumed to be a tare regardless of the gross weight present on the scale at the time of the final transaction. Net values can therefore be negative if the weight on the scale is less than the tare value.
If net sign correction is enabled, the terminal will switch the gross weight and tare weight fields when necessary, so that the larger weight is the gross weight, the smaller weight is the tare weight, with the difference always a positive net weight. Net sign correction affects the display and printed data.
register value is 53 kg and the live weight on the scale is 16 kg.
Table 2-9: Weight Values With and Without Net Sign Correction
Net Sign Correction
Printed and Displayed Disabled Enabled
Gross 16 kg 53 kg
Tare 53 kg 16 kg
Net
37 kg 37 kg
Automatic Tare
The T72XW can be configured so that tare is automatically taken (auto tare) after the weight on the scale exceeds a programmed tare threshold weight. Auto tare can be configured in setup as enabled or disabled. When auto tare is enabled, the display changes to a zero net weight indication after the weight exceeds the threshold value. The previous weight on the scale is stored in the Alibi Table as the tare value. Auto tare operations involve:
Tare Threshold Weight
– When weight on the scale platform exceeds the tare threshold value, the terminal automatically tares.
Reset Threshold Weight
– The reset threshold weight must be less than the tare threshold weight. When the weight on the scale platform falls below the reset threshold value, such as when a load has been removed, the terminal automatically resets the auto tare trigger.
EN 24 7000 SERIES INDICATORS
Motion Check
– A motion check is provided to control the re-arming of the auto tare function. If disabled, the auto tare trigger will be reset as soon as the weight falls below the reset value. If enabled, the weight must settle to no-motion below the reset threshold before the next auto tare can be initiated.
Several conditions could inhibit the auto tare function:
Motion
– Auto tare cannot be taken when the scale is in motion. If motion is detected after the weight on the scale exceeds a preset tare threshold weight, the T72XW will wait for a no-motion condition. If a stable (no motion) weight condition occurs within three seconds, the auto tare command is executed.
Auto Tare Disabled
– Auto tare can be configured in setup as enabled or disabled.
Clearing Tare
Tare values can be cleared manually or automatically.
Manual Clear
Manually clear tare values by pressing the CLEAR key on the numeric keypad when the T72XW is in the net mode and has completed the weighing operation. Motion on the scale will not impact a manual clear.
If configured in setup, pressing the ZERO scale function key will first clear the tare, then issue a zero command (see Chapter 3, Configuration: Terminal, the Scale section, Auto Clear).
Auto Clear
The T72XW can be configured to clear tare automatically when the weight returns to a value below a programmable threshold, or when a print command is issued. Once the tare is cleared, the display returns to the gross weighing mode.
Auto clear is disabled or enabled in setup. If auto clear is enabled the following parameters, configured in setup, affect the auto clear operation:
Clear Threshold Weight
– The clear threshold weight is the gross weight value below which the T72XW will automatically clear a tare after settling to a value above this threshold value.
Motion Check
– A motion check is provided to control the automatic clearing of tare. If the motion check is disabled, the tare value is cleared as soon as the weight drops below the threshold weight (auto clear threshold), regardless of the motion status.
If the motion check is enabled, after meeting the requirements for weight value above and then below the threshold weight (auto clear threshold), the T72XW waits for a no-motion condition before automatically clearing the tare.
Clear After Print
– If enabled, tare is automatically cleared and the scale returned to the gross mode after data has been transmitted by pressing the ENTER/PRINT key or from a remote source.
Refer to the Scale, Auto Clear section of Chapter 3, Configuration: Terminal, for further information about configuring auto clear.
2.4.3 Unit Switching
In order to support locations and applications that utilize multiple measurement units, the T72XW supports unit switching. The SWITCH UNITS key alternate units.
enables switching between primary units (the main unit of measure) and
When the SWITCH UNITS key is pressed, the display changes from the primary unit to the second unit.
When this softkey is pressed again, the display returns to the primary unit. Each subsequent time the SWITCH
UNITS key is pressed the T72XW continues to switch the unit.
When units are switched, the units value changes to the correspondingly selected units, and the conversion of the display value occurs. The display division changes to an equivalent weight value in the switched unit (for example, from 0.02 lb to 0.01 kg) and the decimal location switches to accommodate the conversion.
7000 SERIES INDICATORS EN 25
When switching units, the capacity of the converted units is dictated by the original number of divisions established in the capacity and increments area of setup. In some situations, this may reduce the capacity of the terminal when converting to second unit.
2.4.4 Expand By 10
selected weight display resolution by one additional digit. For example, a weight display of 40.96 could increase by one additional digit to display as 40.958. The Expand By Ten mode is indicated on the display by x10, which displays below the weight display. When Expand by Ten is selected again, the display reverts to the normal display of weight.
If programmed as approved with the metrology switch (SW1-1) ON, the Expand by Ten mode is displayed for five seconds then automatically returns to normal resolution. Printing is disabled when the weight is expanded and the terminal is programmed as approved.
2.4.5 Print
The print function (demand print) can be initiated by pressing the ENTER/PRINT key or by automatic print settings. Demand printing of data may also be initiated as part of a particular sequence of operation or special application software.
Print Interlock
Print Interlock is designed to enforce a single print output per transaction. Print Interlock can be disabled or enabled. If enabled, the print command is ignored until the measured gross weight exceeds the print interlock threshold. A print command initiated before the measured gross weight exceeds the print interlock threshold returns a Command failed
– scale not ready error in the system line.
After the first print command is executed, subsequent print commands are ignored until the gross weight indication falls below the print interlock reset threshold. If a print command is blocked by print Interlock, a Command failed
– scale not ready message appears in the system line.
Automatic Print
Automatic initiation of a demand print occurs after the gross weight exceeds the minimum threshold and there is no motion on the scale. After initiation, the gross weight must return below the reset threshold before a subsequent automatic print can occur.
Automatic print may be disabled or enabled. Automatic print can be triggered and reset by weight exceeding thresholds or by weight deviation from a previously stable reading.
2.4.6 Information Recall
A limited number of data fields are made available for easy recall on the terminal display. These fields include data such as model, serial number, identification fields, hardware and software configuration, a service contact phone number and whether the terminal has been set up as approved for legal for trade operation.
All this data is accessible under the Information Recall icon in the OPERATOR menu.
2.4.7 ID Entry
The ID function is used for two different purposes, depending on whether the terminal is in basic weighing mode or in one of the application modes.
In basic weighing mode, a single ID field is available for transaction identification purposes, and the ID value will be shown at the bottom left of the display. The ID may also be included as a print field in any of the print templates.
When the terminal is running one of the applications, the ID key may access records from an application table.
The basic weighing transactional ID value can be entered using one of two methods, described below.
EN 26

To clear the ID field, press the ID key and when the previous ID value is displayed in focus in the entry box, press the CLEAR key .
2.4.8 Time and Date
Select the TIME & DATE menu item in the Terminal > Region menu and press ENTER to display the Set Time &
Date screen (Figure 2-4). When the time is set, seconds are set to 0.
Depending on the terminal’s time and date format settings, the following values can be entered. Time and date formats, including date field separators, are configured in setup at Terminal > Region > Format Time & Date.
Unless otherwise noted, all values are numeric entries:
Hour, AM/PM (if 12-hour time selected)
Minute
Day
Month (selected from a list)
Year
Although the format for the time and date can be selected according to local preferences (in Setup at Terminal >
Region > Format Time & Date), the use of a timestamp in log files is not selectable. Timestamp formats are always fixed as:
Time: HH:MM:SS stored in 24 hour format (for example, 10:01:22 PM becomes the fixed format time 22:01:22)
Date: YYYY/MM/DD (for example, July 23, 2005 becomes the fixed format date 2005/07/23)
2.4.9 Totalization
Knowing how many weighing transactions were performed and how much material was processed during a particular period of time is useful information for many weighing applications.
The T72XW terminal provides both grand total (GT) and subtotal (ST) registers and counters. Counters have a limit of 1,500,000 and registers will accumulate up to 11 digits of weight, including any digits to the right of the decimal point. For example, a scale programmed for 500 x 0.1 kg will accumulate weight values up to 9999999999.9 (11 total digits). If either of these limits is exceeded, an error message will display and the totals must be reset before additional weights or counts will be added.
2.4.10 Alibi Memory
The Alibi Memory stores transaction data that can be retrieved in order to verify transaction information.
Information stored in the Alibi Memory includes:
Transaction counter value
Date and time of transaction
Gross, net, and tare weights including units of measure
If the T72XW terminal has been programmed as “approved”, Alibi Memory enabling or disabling is only accessible if the security switch (SW1-1) is in the OFF position.

The Certificate field enables entry of the W&M certificate number for the region. This data is shown on the
Information Recall screen along with other approval information. Enter the certificate number (an alphanumeric string of up to 16 characters) in the entry box.
Capacity and Increment
Use the Capacity and Increment setup screen to select primary units, set the number of weighing ranges, and the scale capacity and increment size.
Primary Units
Set the primary units from the selection box choices, which include:
Grams (g) Pounds (lb) Tons (ton)
Kilograms (kg) Tonnes (t)
#Ranges
Set the number of ranges to either one or two in the selection box. If two is selected, the increment size will change when the weight reaches the second range. The weighing ranges are entered next.
>|1|< Capacity
Specify the weight capacity for range 1. If only one range is enabled, this will be the scale capacity and the display will show an overcapacity graphic if the weight exceeds this value by more than five increments. If two ranges are enabled, this will be the weight at which the increment size changes from the range 1 increment size to the range two increment size.
>|1|< Increment
Specify the increment size for weighing range 1. If only one range is enabled, this will be the increment size for the entire weighing range of the scale. If two ranges are enabled, this will be the increment used in the lower range.
>|2|< Capacity
Specify the weight capacity for range 2. If only one range is enabled, this parameter will not be shown. If two ranges are selected, this will be the scale capacity and the display will show an overcapacity graphic if the weight exceeds this value by more than five increments.
>|2|< Increment
Specify the increment size for weighing range 2. If only one range is enabled, this parameter will not be shown. If two ranges are selected, this will be the increment size for the second weighing range of the scale.
To use multiple range mode, the ration of range 2 increment to range 1 increment must be less than 50.
Calibration
The Calibration screen enables entry of a GEO code adjustment value, linearity adjustment, and provides access to zero and span adjustments.
GEO Code
Enter the GEO code for the appropriate adjustment value for the current geographical location. GEO codes are numbered 0
–31. (Refer to Appendix E.)
Linearity Adjustment
Select if a linearity adjustment will be used during calibration. Selections are as follows:
Disabled
– Use only zero and one span point
Enabled
– Use zero, mid span point, and high span point
EN 34 7000 SERIES INDICATORS
Set Zero
The Set Zero function in the Calibration setup triggers an independent operation to reset the zero condition of the scale. A status message displays when this function is accessed that directs the user to empty the scale and press the ENTER key. The status of the capture zero operation displays. When the operation is complete, a final status message displays that verifies the completion of the capture zero operation.
If motion is present during the zero capture process, the terminal will average the weight readings then display a message indicating unstable weight values were used. This message must be acknowledged to save the values.
Set Span
The Set Span function in the Calibration setup initiates a sequence to capture span that can be performed independently of capturing zero.
To capture span:
1. With focus on the Set Span label, press ENTER. The Capture Span setup screen displays
2. Enter the weight for test load 1 (and test load 2 if linearity has been enabled). Press the ENTER key
3. Place test load weight 1 on the scale.
4. With focus on the Place xxxx, press ENTER text, press the ENTER key. The status of the weight capture operation displays. When the operation is complete, a status message displays that verifies the completion of the weight capture.
Press the LEFT navigation key if the calibration process must be aborted and the display will return to the previous screen.
5. After the first calibration step has completed, the menu will either display a prompt for the next calibration weight to be added (if linearity adjustment parameter is enabled) or will show a successful or failed calibration sequence
If motion is present during the span capture process, the terminal will average the weight readings then display a message indicating unstable weight values were used. This message must be acknowledged to save the values.
6. Repeat steps 3 and 4 for test load 2 if enabled by linearity adjustment.
7.
If the capture span operation was successful, a verification message that reads “Capture Span OK” displays If the capture sp an operation was not successful, an error message that reads “Calibration Failure” displays. If the calibration fails, repeat the capture span procedures. If the calibration continues to fail, contact a local
OHAUS CORPORTATION representative for assistance.
8. Press the LEFT navigation key to return to the Calibration screen.
Analog Saturation Test
During the calibration process, the T72XW will determine if there is a potential for analog section saturation. The
T72XW will compare the available number of counts with the captured span to confirm that the desired capacity is achievable. If the potential exists to saturate the analog section before system capacity is reached, the T72XW will display a warning message and recommendation that the system be recalibrated with a new, lower, capacity.
Figure 3-10: Analog Saturation Warning
7000 SERIES INDICATORS EN 35
This message functions only as a recommendation to recalibrate. After the warning message is acknowledged by pressing the ENTER key, the user is presented with the “Capture Span OK” screen. Service personnel should then carry out the following:
The scale should be recalibrated with a lower capacity. Potential analog section saturation does not force a failure in calibration.
IMPORTANT: It is critical that service personnel follow the recommendation to recalibrate. Analog section saturation will result in a ‘freeze’ of the display, where the display no longer shows increases in weight, creating the possibility of overfills and spills during the weighing process.
Zero
This section provides access to Auto Zero Maintenance (AZM) settings, under zero blanking, power-up zero, and pushbutton zero parameters.
Auto Zero
AZM is a means of tracking zero when the scale is empty. AZM compensates for conditions such as terminal or load cell drift or debris on a scale platform.
Use the Auto Zero setup screen to enable auto zero for gross weighing or gross and net weighing, or to turn auto zero off.
Auto Zero Range
Set the auto zero range for the number of divisions (d) around the current zero setting in which auto zero will operate. Selections include 0.5, 1, 3 and 10 d.
Under Zero Blanking
When Under Zero Blanking is set to Disabled, the terminal displays a negative weight as far below zero as possible when the weight goes under gross zero. Other options are:
20d The terminal displays a negative weight until 20 divisions below zero, and then blanks the display.
20d with Zero The terminal displays a negative weight until 20 divisions below zero, and then blanks the display. The display remains blanked until the scale is manually zeroed. This feature is required for approval in Thailand.
Power Up Zero
A Power Up setting of Disabled enables the terminal to save and reuse the last zero reference weight after a power cycle so it returns to the same gross or net weight value. If a power up range of +/-2% or +/-10% is selected, the terminal tries to capture zero upon power up.
For example, if the setting for Power Up Zero is set at 2%, Power Up Zero will only occur when the weight reading on the scale is within +/- 2% of the original calibrated zero condition.
If Power Up Zero capture is enabled and the weight on the scale is outside of the zero capture range, the display will indicate [ E E E ] until the weight is removed and zero is captured.
Pushbutton Zero
If Pushbutton Zero is Disabled, the front panel ZERO pushbutton will not operate to capture a new zero reference point. If a range of +/-2% or +/- 20% is selected, pushbutton zero will operate within the selected range to rezero the scale.
If Pushbutton Zero is Disabled, execution of a remote Zero is still possible via SICS or CPTZ commands from a PC and a discrete input command.
For example, if the setting for Pushbutton Zero is set at +/-2%, the Pushbutton Zero can only be used when the weight reading on the scale is within +/- 2% of the original calibrated zero condition.
EN 36 7000 SERIES INDICATORS
Tare
Tare is used to subtract the weight of an empty container from the gross weight on the scale to determine the net weight of the contents. Tare is inhibited if the scale is in motion.
Three setup screens are available to configure tare:
Auto Tare Auto Clear Tare Types
Tare Types
Use the Tare Types setup screen to enable or disable pushbutton tare, keyboard tare, and net sign correction.
Pushbutton Tare
When pushbutton tare is Enabled, the TARE scale function key can be pressed when an empty container is on the scale to determine tare. The terminal displays a zero weight and net mode. When the container is loaded and placed back on the scale, the terminal displays the net weight of the contents.
If Pushbutton Tare is Disabled, execution of a remote Tare is still possible via SICS or CPTZ commands or from discrete input command.
Keyboard Tare
When keyboard tare is Enabled, the known value for the empty weight of a container (tare) can be entered manually. The terminal will then display the net weight of the contents of the container. Keyboard tares are automatically rounded to the closest display division.
Net Sign Correction
Net sign correction enables the T72XW terminal to be used for both shipping (inbound empty) and receiving
(inbound loaded) operations. If net sign correction is Disabled, the terminal will display and print a negative net weight when the tare weight is larger than the gross weight. If net sign correction is Enabled, the terminal will switch the gross and tare weight fields on the printed ticket, if necessary, so that the larger weight is the gross weight, the smaller weight is the tare weight, and the difference is always a positive net weight. Net sign correction affects the printed data output and the displayed weight. Continuous data output will continue to show a negative net weight value.
Net sign correction will operate with pushbutton tare and preset tare. An example of weight values with and without
scale is 16 kg.

Net 37 kg
When net sign correction is enabled, the tare weight field in the recall display will be labeled with the letter “M” to indicate “Memory” instead of “T” or “PT”.
Auto Tare
Use the Auto Tare screen to enable or disable automatic tare, to set the tare and reset threshold weights, and enable or disable motion check.
Auto Tare
When auto tare is Enabled, the tare weight is taken automatically when a container above the threshold weight is on the scale and settles to no-motion. Set to Disable if automatic tare will not be used.
Tare Threshold Wt.
7000 SERIES INDICATORS
When weight on the scale platform exceeds the tare threshold value and settles to no-motion, the terminal automatically tares.
Reset Threshold Weight
EN 37
When the weight on the scale platform falls below the reset threshold value, such as when a load has been removed, the terminal automatically resets the auto tare trigger, depending upon the programming of motion checking. The reset threshold weight must be less than the tare threshold weight.
Motion Check
Enable the motion check setting to prevent auto tare reset rigger from occurring when the scale is in motion. When enabled, the scale must detect a non-motion condition below the reset value to reset the auto tare trigger.
Auto Clear
Use the Auto Clear screen to Enable or Disable auto clear tare, clear after print, to set the clear threshold weight, and enable or disable motion checking for auto clearing of tare.
Auto Clear Tare
To clear tare automatically when the scale returns to below the threshold weight, enable the auto clear tare setting.
Clear Threshold Wt.
When the gross scale weight exceeds then falls below the clear threshold weight value, the terminal automatically clears tare and returns to gross mode.
Motion Check
Enable the motion check setting to prevent auto clear from occurring when the scale is in motion below the threshold weight.
Clear After Print
The Clear After Print field displays only when Auto Clear Tare is enabled. To clear tare automatically after printing,
Enable the clear after print setting. Select Disable to not clear tare after a print.
Units
This setup screen enables the selection of a second unit.
Second Unit
Use the Second Unit selection box to select a second weighing unit or to select none. The weight will be converted from primary to the selected secondary unit when the Units Switch key is pressed.
Available weighing units include:
Grams (g) Pounds (lb)
Kilograms (kg)
Ounces (oz)
Tonnes (t)
Tons (ton)
Filter
The T72XW terminal has a low-pass, multi-pole vibration filter that can be set for several conditions. The heavier the filtering, the slower the display settling time will be.
Low Pass Filter
Low Pass filter selections include Very Light, Light, Medium (default) and Heavy. This parameter sets the amount of filtering that is applied to the weight. The heavier the filter applied, the more stable the weight will be, but the longer the settling time required for the scale.
Stability Filter
The stability filter works in conjunction with the standard low pass filter to provide a more stable final weight reading. The stability filter should only be used in transaction weighing applications, since the nonlinear action of the filter switching may cause inaccurate cutoffs in filling applications. The stability filter can be Enabled or Disabled on this setup screen.
Stability
The T72XW terminal includes a stability detector (weight in motion). The Stability setup screen enables setting a motion range, no-motion interval and timeout period.
Motion Range
Sets the motion range of the weight value (in divisions) that the weight is permitted to fluctuate and still have a nomotion condition. Select a value from Disabled, 1d or 3d. If the motion range is disabled, motion detection is disabled and the scale will never indicate motion.
EN 38 7000 SERIES INDICATORS
No-motion Interval
The no motion interval defines the amount of time (seconds) that the scale weight must be within the motion range to have a no-motion condition. Select a value from 0.3, 0.5, 0.7 or 1.0 seconds. A shorter interval means that a nomotion condition is more likely, but may cause the terminal to indicate no-motion while there is still a small amount of motion on the scale.
Timeout
Defines the period (in seconds) after which the terminal stops attempting to perform a function that requires a nomotion condition (such as a zero, tare or print command) and aborts the function. This timeout is used regardless of the source of the command such as the keypad, discrete input or SICS. Select a values from Disabled, 3, 10 or 30 seconds, the default value being 3. A smaller value means that less time will be used to check for no-motion before aborting a command. When disabled is selected, the terminal will wait indefinitely for a no-motion condition - a command would never be aborted.
Log or Print
The Log or Print setup branch is where the thresholds to control how and when data is saved or output to a printer are defined. Normal demand mode printing occurs whenever a print request is made, providing there is no motion on the scale and zero has been captured.
The weight values entered are the gross weight values in primary units. Gross weight in primary units is used regardless of whether the T72XW is in Gross or Net mode and regardless of the units that are displayed.
Minimum Weight
The minimum weight setting is the threshold below which log or print functions will not initiate. A value of 0 permits printing when any weight value is shown (not blanked over capacity or under zero.
Interlock
Interlock prevents repeat logging and printing without a weight change. If Enabled, interlock requires that the weight reading be reset p er the “Reset on” parameter setting (see below) and then settle to a weight greater than the minimum print value before responding to the next log or print request. If Disabled, multiple prints of the same weight are possible
.
Automatic
Enable the automatic setting to automatically log data and print every time the weight on the scale settles to a positive value that is larger than the entered threshold weight value.
If Automatic is set to Disabled, the Threshold Weight field does not appear and a print or log of data must be triggered manually.
Reset on
The resetting of auto printing or logging can be based on weight threshold or weight deviation values. Select Return
(the weight must return to below this value to reset) or Deviation (the weight must change more than this value to reset) from the selection box and enter the weight value in the “Reset on” field.
If both “Interlock” and “Automatic” settings are disabled, the “Reset on” field does not display.
If “Reset on” is set to Deviation, The “Threshold Weight” and “Motion Check” fields do not display.
Threshold Weight
The Threshold Weight is the value above which an Automatic logging or printing of data can/will occur. Threshold
Weight does not appear if “Automatic” is set to Disabled or if “Reset on” is set to Deviation.
Motion Check
Enable the motion check setting to prevent interlock and automatic log and print functions from resetting when the scale is in motion below the “Reset On” return point. Motion Check does not appear if “Reset on” is set to
Deviation.

Application branch. Each of these setup parameters are described in this section.
Figure 3-11: Application Branch Menu Structure
Memory
Memory setup screens includes parameters for Alibi memory.
Alibi Memory
The Alibi Memory can be Enabled or Disabled in the selection box. Alibi memory is configured as a “ring” buffer that overwrites the oldest record when it reaches its memory limit. Each time a demand print is triggered, specific data fields are stored in Alibi memory. Alibi memory can hold approximately 60,000 transactions before it reaches its limit and begins overwriting old transactions. More detailed information about Alibi memory can be found in
Appendix D, Alibi Memory Structure.
EN 40 7000 SERIES INDICATORS
The use of Alibi Memory requires installation of an SD memory card. Attempts to generate a print transaction from the front panel without an SD card installed return a pop-up error message SD card is not installed., while a print command issued serially or via an input will result in an SD memory card not installed message in the system line.
The transaction counter will not increment.
The Alibi Memory table stores basic transaction information that is not user-definable. This information always includes:
Date and time stamp
Transaction counter value
Gross, tare, and net weights and weight unit
If the T72XW terminal has been programmed as “approved”, Alibi Memory enabling or disabling is only accessible if the security switch (SW1-1) is in the OFF position.
Totalization
Use the Totalization setup screen to select parameters for totalization operations, including which source to use as input for totalization, settings for grand totals and subtotals, and to enable or disable the conversion of second unit weights for totalization. When a demand print occurs, the selected weight field will be added to the totals register.
Mode
Select which source to use as input for totalization comparison
– either Displayed Weight or Gross Weight. A selection of None disables totalization.
Clear GT on Print.
The Grand Total can be configured to clear automatically after printing the Totals report. If Clear GT on Print is
Enabled, the subtotal also clears automatically after printing the Totals report.
Subtotal
The Subtotal can be separately disabled while the GT continues to accumulate weights. Choose to either Enable or
Disable the subtotal register.
Clear ST on Print
Clearing the subtotal on print and not clearing the grand total on print allows the subtotal register to totalize subsets of weighments and to be reset while the grand total continues to track the grand total of weight. Choose to
Clear ST on Print or not by selecting Enabled or Disabled in the selection box..
Convert Weight
The total registers always store weights in primary units. If Convert Weight is Disabled, scale weights other than primary units are not accumulated. If Convert Weight is Enabled, then the weight is converted to primary units, then accumulated.
Discrete I/O
Discrete I/O setup menus allow the configuration of 2 inputs and 4 outputs. The Discrete I/O option must be installed to program this functionality.
Inputs
The Discrete Input menus display discrete input polarity and assignments for Input 1 and Input 2. The two Inputs are configured in the same way.

Templates
The T72XW terminal provides three different output formats available to demand outputs. Each of these formats is created in a template. A template supports up to 25 data fields to define the format of a demand data output. In addition, each application has at least one template dedicated to it. So, a total of 9 templates are supported in the
T72XW.
A template strings setup screen is also available to configure strings of characters that are frequently used in templates such as a customer name or address.

Each of the application templates is configured as described above, using the field number and item. Each application also provides new application-specific items that can be added to a template. The additional items for each template are listed in Chapter 4.
Add Line Feeds
On each template page is an entry box for entering the number of blank lines to be added at the end of the template. This provides the ability to advance a ticket or label after printing. Enter a value from 0 to 9 for the number of line feeds to be added after a template is transmitted.
Strings
The Template Strings setup screen defines up to 10 strings of characters that may be used in template messages.
Template strings can be viewed, edited or cleared.
To enter or edit template strings:
Select the string number in the first selection box then any existing data for that string will be shown in the second entry box. Using the alphanumeric keys, enter or edit the characters to be used as the selected string.
Note that there is a new method of data entry called Decimal supported in Template Strings. The SHIFT key now switches between numeric entry , upper case alpha entry , lower case alpha entry , and decimal entry . The decimal entry method can be used to enter specific characters not available via the
T72XW alphanumeric keypad by entering the decimal value of the ASCII character. This is also useful when preparing a template for a printer that uses a different character set to print international characters. By entering the decimal value of the international character, new ASCII characters can be transmitted. When decimal entry is selected, an entry box below the string entry box will be shown. Enter the two or three digit decimal number for a special character and then press ENTER. To exit the decimal entry mode, press the SHIFT key and the decimal entry box will be removed and focus moves back to the string entry box.
EN 50 7000 SERIES INDICATORS
Note that decimal values from 32 to 255 can be entered. Control characters in decimal values 0 to 31 cannot be entered using this method. Control characters can be included in a template created using the InSite software. They will be recognized by the T72XW when the template is downloaded, and will be included in the template when it is printed
When entry is complete, press ENTER and focus will move back to String #. It is then possible to select another string to enter or edit.
Reports
The reports setup screen enables configuration of the structure of reports that are generated by the T72XW terminal. The reports setup screens include width, header, record separator and footer selections.
Width
Use the selection box for the Width field to select the width of the reports
Narrow (40)
– 40 character-wide reports
Wide (80)
– 80 character-wide reports
Header
The Header field specifies the number of blank lines (CR/LF) to be placed at the start of each report.
Record Separator
A repeated character may be selected as a separator between printed records in the report. This step selects the character to be used. The character choices in the selection box are:
None (no separator between records) = (equal symbols)
* (asterisks) CR/LF (blank line)
- (dashes)
For example, if * (asterisks) is selected, the resulting line separator will appear as follows:
*************************************************************************
Footer
The Footer field specifies the number of blank lines (CR/LF) to be placed at the end of each report.
Connections
The connections setup provides a method to assign a function to a physical port in the terminal. The optional ports are only available if the appropriate option board has been installed.
Setup pages are available for the COM1, COM2, USB and Ethernet ports in the T72XW terminal.
These screens define what type of communication will occur over each port. If no connections are programmed, there will not be any data communication on that port. Specific details of the different assignments can be found in
Appendix E, Communications.
It may be required that one port support a demand output from basic weighing, a demand print from an application and maybe a report print. To support this capability, if the first Assignment is Demand or Report, a second assignment is made available (Assignment 2). If Assignment 2 is programmed for Demand or Report, then a third assignment (Assignment 3) will be available. If an assignment is programmed as anything except Demand or
Reports, then no additional assignments will be possible.
Depending upon the assignment for a port, a template or checksum setup parameter will be shown. Refer to
Table 3-5 for a list of the possible assignments for each port and the additional setup parameters required for that assignment.

Each of the following sections details operating procedures, operational features and function for the five applications included in the T72XW terminal.
For information on general operation of the T72XW terminal, please refer to Chapter 2, Operation: Terminal.
For information on general configuration of the T72XW terminal, please refer to Chapter 3, Configuration: Terminal.
4.2 Animal Weighing
4.2.1 Overview
The Animal Weighing application provides the ability to calculate and display an average weight value determined over a user-defined sampling period. This is useful when the weight is constantly unstable, as in the case of weighing live animals.
Two modes of operation are supported in the animal weighing application. One mode simply determines the average weight on the scale regardless if a single animal or multiple animals are on the scale. The second mode is designed for weighing multiple animals and provides the average weight per animal in addition to the total average weight of all animals. The application provides the following:
Simple, one key operation
Prompts for start of weighing cycle
Weight averaged over variable sampling time period
Display of remaining time in cycle
Final average weight display and print
When the FUNCTION key is pressed from the basic weigh mode the initial Animal Weighing display screen will be shown. The
FUNCTION
icon in the lower left corner indicates the Animal Weighing application mode. Pressing the
key again will return the terminal to display the basic weighing mode.
4.2.2 Operational Features
In addition to the fundamental weighing functions, the following T72XW terminal basic weighing features can also be used within the Animal Weighing application.

Function
Application determines the average total weight on the scale
Application determines the average total weight on the scale and calculates the average weight per animal
The default value is 1.
Sampling Time
The Sampling Time setting determines the amount of time over which the scale will sample the weight on the scale in order to determine an average total weight.
The value is entered using the alphanumeric entry keys. Valid settings are from 1 to 9.9 seconds, in 0.1 second increments. The default value is 5.0.
Auto Start
When enabled, Auto Start begins the weighing process when the weight on the scale exceeds a minimum weight defined by the Start Threshold, and has reached stability. When the process is complete, the weight must fall below
20d (display divisions) and then exceed the threshold again to start the next cycle.
This feature can be Enabled or Disabled. By default, it is Disabled.
7000 SERIES INDICATORS EN 61
Start Threshold
The Start Threshold appears in the menu tree only when Auto Start is Enabled. It defines the scale weight value above which the averaging process will begin after stability is reached.
Valid settings are from 0 to the full scale capacity. This value should be relatively high
– for example, 80% of the estimated weight of all animals on the scale. A very low number may cause the sampling period to start before all the animals are on the scale.
Auto Print
This Auto Print setting overrides the basic weighing Auto Print function, configured in setup at Scale > Log or Print
> Automatic when operating within the application.
When Auto Print is enabled, the processed weight value is displayed for the amount of time defined by the Print
Delay setting, and then a transaction print is automatically triggered.
This feature can be Enabled or Disabled. By default, it is Disabled.
Print Delay
Print Delay is only shown in the menu tree when Auto Print is enabled. It determines the delay between completion of the transaction and triggering the transaction print.
Valid settings are from 0 to 10 seconds in 1 second increments. The default value is 5.

4.3 Checkweighing (Over/Under)
4.3.1 Overview
In the Over/Under application, the T72XW compares weight on the scale to a stored target weight, and indicates the status of the comparison on screen.
The application can also control external equipment, such as status lights, using three external outputs for Under,
OK and Over. This application provides the following features and functions:
Very fast weight response
Three zone status (Under, OK, Over) with SmartTrac
®
graphical representation of status on display
Storage of up to 25 target weights by ID for quick recall of target values
Optional discrete output signals for remote status lights
When the FUNCTION key is pressed from the basic weigh mode the initial Checkweighing display screen will be shown. The icon in the lower left corner indicates the Checkweighing application mode. Pressing the
FUNCTION key again will return the terminal to display the basic weighing mode.
4.3.2 Operational Features
In addition to the fundamental weighing functions, the following T72XW terminal basic weighing features can also be used within the Checkweighing Weighing application.
Auto-Print
If the T72XW checkweighing application is used to assess the weight of a series of items, enabling Auto-print will automatically generate a demand output of the weight data and comparison status once the scale weight is above the threshold value and is stable. The Checkweighing application shares the auto print features of the basic weighing mode.
ID
If an ID value is entered in the basic weighing mode, it remains available for printing when in the Checkweighing mode. However, within the Checkweighing application the ID function is used only to retrieve target records by ID.
7000 SERIES INDICATORS
Tare
EN 65
A semi-automatic tare can be taken any time during the weighing cycle. Simply press the TARE key.
A preset tare value can be entered using the numeric keypad. Use the numeric keys to enter the preset tare value.
The digits will appear in line 2 of the lower part of the display, below the “Data:” prompt. When tare entry is complete, press TARE
Discrete I/O
to accept the value.
The Checkweighing application supports three new discrete outputs.
The three new outputs are Under Zone, OK Zone and Over Zone:
The Under Zone output turns ON when the weight on the scale is below the target minus the
– tolerance value.
The OK Zone status turns ON when the weight on the scale is above the target minus the
– tolerance value and below the target plus the + tolerance value.
The Over Zone output turns on when the weight on the scale exceeds the target plus the + tolerance value.
Target Table Import and Export
The OHAUS CORPORTATION T72XW File Transfer Tool (FTT) program, included on the T72XW Resource CD-
ROM, runs on a PC to exchange application files and tables with the T72XW terminal. Refer to the User's Guide of the File Transfer Tool for details.
4.3.3 Configuration
The FUNCTION key must be programmed for Checkweighing in setup at Application > Function Key >
Assignment in order for this application to operate and to access the setup steps for the Checkweighing application.

Source
EN 66 7000 SERIES INDICATORS
Source may be set as Displayed Weight (the default) or Gross Weight. If Displayed Weight is selected, the over/under function will work based on the displayed weight, either gross or net. If gross weight is selected, the target comparison will be based on the gross weight even if a tare is taken and a net weight is displayed.
Tolerance Type
The Tolerance Type can be Target Deviation (the default), % of Target or Weight Value. This setting determines the type of tolerance to be used in calculating the weight status. Target Deviation provides both + tolerance and
– tolerance weight values. % of Target is similar to Target Deviation except the tolerances are entered as percentages instead of weights. Weight Value eliminates the target entry and allows direct entry of the Under Limit and Over Limit values which equate to the minimum and maximum acceptance values.
Target Editing
The Target Editing parameter determines which active target values can be edited when accessed from the
Operator Menu. Options are Target & Tolerance (the default), Target Only and Disabled.
Values are always editable from within setup, but only values selected as editable can be modified from the
Operator Menu. Values not selected as editable can only be viewed.
The Description field can be edited if either Target Only or Target & Tolerance is selected.
If Target Editing is selected as Disabled, none of the values can be edited in the Operator Menu.
Hold Timer
The Hold Timer is a value, between 0.0 and 9.9 seconds, that sets the amount of time for which the display will freeze after a print command, before returning to the live display. If a second print command is issued during the set period, it will over-ride the existing count, the new current value will display, and the display will freeze again for the set time.
During the hold time, an asterisk (*) is shown on the display to indicate the weight is not live.
Motion Check
The Motion Check parameter can be Disabled (the default) or Enabled. When Enabled, the discrete outputs for
Under, OK and Over and the zone indication on the display will turn ON only when no motion is detected. When
Motion Check is Disabled, the corresponding output and zone indication display will turn on when the zone edge is reached, regardless of motion.
Display
Display Mode
This parameter determines what will be displayed in the main display area
– Actual Weight (the default), Target

SmartTrac
The graphic zone display of the results of the target comparison can be Enabled (the default) or Disabled.
If Line 1 is Disabled and SmartTrac is Enabled, the SmartTrac graphic will expand to occupy both lines of the lower display.
Motion Blanking
If Motion Blanking is Enabled, the numeric weight display will be blanked when the scale is in motion, and will only display a weight value when the scale is stable. Motion Blanking is Disabled by default.
Menu Keys
The Menu Keys parameters determine which functions will be accessible from the Operator Menu.
7000 SERIES INDICATORS EN 67
If the feature accessed by the key must be enabled or configured separately, such as the Target Table, enabling its menu key will display the corresponding icon in the Operator Menu, but will not give access to the feature.
Active Target
By default, the Active Target is Enabled, so that the active target and tolerance values in use can be viewed by the
Operator. The Target Editing parameter at Operation > Target Editing determines which of the viewable fields can be edited.
Quick Set Target
Disabled by default, Quick Set Target can be Enabled to permit the Operator to define a new target by placing actual weights on the scale.
Target Table
Operator access to the Target Table can be Disabled (the default) or Enabled.
Target Values
Selecting Target Values opens a screen that displays the current target information. The appearance of this screen will vary depending on the Tolerance Type selected under Operation:
If the Tolerance Type is set to Target Deviation or % of Target, the screen will include a target value together with upper and lower tolerances, expressed either as a weight value or a percentage of the target, and the
Description field.
If the Tolerance Type is Weight Value, the Under Limit and Over Limit are displayed, together with the
Description field.
Each value is updated when focus leaves the entry box.
Note: Disabling all of the target menu keys will prohibit an operator from viewing or changing the target and tolerance values. These values can still be entered and edited in setup at the Target Values page.
Target Table
The Target Table can store up to 25 target IDs, each with its own target and tolerance values together with a description and (if Totalization is enabled) a total register and transaction counter. The target ID can be used for the quick recall of a set of target parameters for Checkweighing.
Note: The first 10 records are stored in memory on the main board and are always available. An SD memory card must be installed to store the remaining 15 records, giving a total of 25.
Target Table
The Target Table can be Enabled or Disabled (the default). If the table is Enabled, the Totalization and Clear Totals parameters and the View Table option also appear on the screen. If the table is Disabled, the ID field in
Checkweighing will refer to the basic weighing ID.
Totalization
Totalization allows the terminal to track the total weight and number of transactions associated with an ID in the target table.
Totalization can be Enabled or Disabled (the default). If it is Enabled, count and total weight values are accumulated for each ID when a demand output with template 6 is generated.
Note: If any parameters of a recalled ID are changed while viewing the active record, the Totalization link will be broken and accumulation will no longer occur.
Clear Totals
Clear Totals can be set to Disabled, Automatic or Manual (the default).

4.4 Counting
4.4.1 Overview
The T72XW Counting application provides a simple counting sequence that guides an operator through a sampling process to determine a count value. The counting application offers the following capabilities:
Operator prompting.
Variable sample entry using the terminal’s numeric keypad.
Average piece weight (APW) entry using the numeric keypad.
Up to 99 stored ID records in the ID Table
Count accumulation by ID.
When the FUNCTION key is pressed from the basic weigh mode the initial Counting display screen will be shown. The icon in the lower left corner indicates the Counting application mode. Pressing the FUNCTION
key again will return the terminal to display the basic weighing mode.
EN 74 7000 SERIES INDICATORS
4.4.2 Operational Features
In addition to the fundamental weighing functions, the following T72XW terminal basic weighing features can also be used within the Counting application.
Semi-Automatic Tare
When the Tare? prompt is displayed on the terminal, press TARE
and the scale will tare to net zero. To take a new pushbutton tare when in counting mode and a number of pieces (PCS) is shown on the display, press the
TARE key . The scale will tare to net zero, and the display will show 0 pieces.

ID
.
If an ID value is entered in the basic weighing mode, it remainsavailable for printing when in the Counting mode.
However, within the Counting application, the ID function is used only to retrieve counting ID records.
Auto-Print
The T72XW’s auto-printing feature is supported by the counting application. If the feature is enabled, a demand output will be sent automatically to the assigned output port when the weight settles to no-motion above the programmed threshold weight. This is a useful feature when counting the same part in the same weight carton repeatedly. By retaining the tare and APW values, a print can automatically be generated simply by removing the previous carton of parts and placing the next carton on the scale.
4.4.3 Configuration
The FUNCTION key must be programmed for Counting in setup at Application > Function Key > Assignment in order for this application to operate and to access the setup steps for the Counting application. When the
FUNCTION key is properly programmed, the Counting branch of setup is displayed as shown in Figure 4-13.
Operation
Prompt
Figure 4-13: Counting Application Configuration Menu
7000 SERIES INDICATORS EN 75
The Prompt setting determines the sequence in which the operator is prompted to enter the tare weight and sample quantity.
Options are Tare-Sample and Sample-Tare. The default is Tare-Sample.
Auto Clear APW
The Auto Clear APW setting determines whether the average piece weight value (APW) will be cleared when the scale returns to zero, or if the APW will be retained for the next counting sequence. Settings are Enabled and
Disabled (the default).
Display
Line 1, Line 2
These parameters determine what is displayed on the two lower lines of the display. Both lines have the same options
– Disabled (the default), ID, Description and APW.
Menu Keys
The Menu Keys parameters determine which functions will be accessible from the Operator Menu. Each of the keys is Disabled by default.
If the feature accessed by the menu key must be enabled or configured separately, such as the ID Table, enabling the menu key will display the icon in the Operator Menu, but will not give access to the feature.
ID Table
When Enabled, the Operator will be able to access the ID Table to retrieve stored tare and APW values for a product.
Reports
When Enabled, the Operator will be able to generate a report of the records in the ID Table to view and print.
Sample/APW Select
When Enabled, the Operator will be able to switch from the sampling mode of operation to manual entry of an APW value mode when prompted for Sample?.
ID Memory
ID Table
When the ID Table is Enabled, stored tare and APW values in the ID Table can be recalled by ID for a quick counting sequence.
Totalization
This parameter appears only if the ID Table is enabled. When Totalization is Enabled, the terminal stores the total number of pieces counted and the number of transactions for each ID in the ID Table. This parameter is Disabled by default.
Clear on Print
This parameter appears only if the ID Table is enabled. Clear on Print may be Automatic (the default), Manual or
Disabled. When Automatic is selected, after the ID Table report is printed, the counter and totals fields will be reset to 0. When Manual is selected, the Operator can choose to clear the counter and totals fields by pressing CLEAR when viewing the ID Table report. If Disabled is chosen, the counter and total fields cannot be reset in the Reports view of the Operator menu.

5 SERVICE AND MAINTENANCE
The T72XW terminal is designed to provide years of dependable operation.
However, OHAUS CORPORTATION recommends that
– as with any industrial measurement equipment – the terminal and the connected scale system be serviced periodically.
Timely, factory-specified maintenance and calibration by a OHAUS CORPORTATION authorized service technician will ensure and document accurate and dependable performance to specifications.
5.1 Cleaning and Maintenance
Clean the terminal’s keypad and cover with a clean, soft cloth that has been dampened with a mild glass cleaner.
Do not use any type of industrial solvent such as toluene or isopropanol (IPA) that could damage the terminal’s finish. Do not spray cleaner directly on the terminal.
Regular maintenance inspections and calibration by a qualified service technician are recommended.
The T72XW terminal is a rugged instrument; however, the front panel is a relatively thin covering over sensitive electronic switches and a lighted display. Care should be taken to avoid any punctures to this surface or any vibrations or shocks to the instrument. If the front panel is punctured, ensure that steps are taken to prevent dust and moisture from entering the unit until the terminal can be repaired.
5.2 Service
Only qualified personnel should perform installation, programming, and service. Please contact a local authorized
OHAUS CORPORTATION representative for assistance.
OHAUS CORPORTATION recommends periodic preventative maintenance to the terminal and scale system to ensure reliability and to maximize service life.

APPENDIX B ALIBI MEMORY
Alibi memory stores transaction information in a preset format that is not changeable. Alibi memory can be enabled or disabled in setup at Application > Memory > Alibi. In order for the Alibi memory to store transaction data, the optional SD memory card must be installed.
The alibi memory operates by storing up to 100 alibi records in a battery-backed file as they occur. When this file is full, each of these records is written to the “alibi.bin” file in flash and the 100-record file is cleared and begins to store the next 100 records. The Alibi memory feature can store up to 60,000 transactions before it rolls over and begins to overwrite the oldest file. When the Alibi memory becomes 75% full, a warning message displays indicating the status. Another message displays when the file is 90% full. It will continue to store records and when it is 100% full, it begins overwriting the oldest records. At this point, new Alibi memory records will be recorded over the older ones.
Each record in the Alibi Memory file includes:
Date and time fields
A transaction counter value, which is a unique numeric field that identifies the transaction (the transaction counter must be enabled in terminal setup to activate the transaction counter value)
Gross or net weight, tare weight, type of tare, and weight unit

APPENDIX C COMMUNICATIONS
C.1 Serial Interface Parameters
One standard serial port and one optional serial port are supported with the T72XW terminal. They are designated
COM1 (standard port on the Main PCB) and COM2 (optional).
COM1 provides an RS-232 interface only. The RS-232 interface is a three-wire (TDX, RXD, and GND) with selectable XON-XOFF handshaking.
Optional COM2 provides RS-232 and RS-485 interfaces. The RS-232 interface is a three-wire (TDX, RXD, and
GND) with selectable XON-XOFF handshaking. The RS-485 connection is a two-wire interface but does not support multi-drop communication with addressing. The port must be selected for use as either RS-232 or RS-485 due to the different operating requirements of the interfaces.
The baud rate can be configured from 300 to 115.2K baud and a checksum character can also be configured when using one of the continuous output strings.
The T72XW terminal supports the following functions on the serial ports:
SICS (level 0 and level 1)
Reports
Variable access (COM1 only)
Continuous
The COM1 port is also used when flashing new firmware to the terminal.
Demand Output Mode
The demand output mode transmits data only when the terminal receives a print request. Print requests are sent to the T72XW terminal when:
The operator presses PRINT
A discrete input selected as print is triggered
An ASCII “P” is sent through a demand or continuous port
Auto print is enabled and all conditions for auto print are met
A print command is sent via shared variable access
When triggered, data is transmitted in a string programmed in the output template portion of setup. Demand mode is used typically when sending data to a printer or PC on a transactional basis.
NOTE: When the demand output mode is assigned, the port is automatically set up to also receive certain ASCII characters to duplicate keypad functions.
Output Templates
The T72XW terminal provides three programmable output templates to define the string of data to be transmitted.
Each of the templates is configured in setup and can contain up to 25 fields of data. The same template can be sent to both COM1 and COM2 if both ports are programmed for demand output. It is also possible to send a different data string from the two ports by assigning a different template to each one.
The detault values for each of the templates follow:
Template 1
29.94 kg
10.32 kg T
19.62 kg N

Continuous Output Mode
Printout string for g, kg, lb, oz units:
Field Weight space Unit space Stability space G/N/T Space
Length 8 1 3 1 1 1 1 1
The printout string has a fixed length of 17 characters.
Each Space field is a delimiting space used to separate the other fields.
The Weight field is 8 right justified characters. If the value is negative, the '‐' character is printed at the
EN 99
immediate left of the most significant digit.
The Unit/Mode field is 3 left justified characters.
The Stability field is 1 character.
The G/N/T field is 1 character. 'G' is printed for a gross weight. 'N' is printed for a net weight.
Note: The Termination Characters Carriage Return and Line Feed are appended to the printout.
C.2 Standard Interface Command Set (SICS) Protocol
The T72XW terminal supports the OHAUS CORPORTATION Standard Interface Command Set (MT-SICS), which is divided into four levels (0, 1, 2, 3), depending on the functionality of the device. This terminal supports parts of levels 0 and 1:
MT-SICS level 0
– Command set for the simplest device.
MT-SICS level 1
– Extension of the command set for standard devices.
A feature of this interface is that the commands combined in MT-SICS level 0 and 1 are identical for all devices.
Both the simplest weighing device and a fully expanded weighing workstation can recognize the commands of MT-
SICS levels 0 and 1.
Version Number of the MT-SICS
Each level of the MT-SICS has its own version number, which can be requested with the command I1 from level 0.
This terminal supports:
MT-SICS level 0, version 2.2x (except the ZI command)
MT-SICS level 1, version 2.2x (except the D, DW and K commands)
EN 100
Command Formats
7000 SERIES INDICATORS
Each command received by the terminal via the SICS interface is acknowledged by a response to the transmitting device. Commands and responses are data strings with a fixed format. Commands sent to the terminal comprise one or more characters of the ASCII character set. Commands must be in upper-case.
The parameters of the command must be separated from one another and from the command name by a space
(20xh), in the examples shown in this section, a space is represented as _ ).
Each command must be terminated by <CR>< LF> (0Dxh, 0Axh).
The characters <CR> and <LF>, which can be input using the ENTER or RETURN key of most PC terminal keypads, are not shown in this description; however, it is essential they be included for communication with the terminal.
Example
Command to tare the terminal:
“TA_20.00_lb” (The command terminators <CR>< LF> are not shown.)
Response Formats
All responses sent by the terminal to the transmitting device acknowledging the received commands have one of the following formats:
Response with weight value
Response without weight value
Error message
Format of the Response with Weight Value
A general description of the response with weight value as follows:
ID
– Response identification.
__
– Space (20xh)
Status
– Status of the terminal. See description of the commands and responses.
Weight Value
– Weighing result, which is shown as a number with 10 digits, including sign directly in front of the first digit. The weight value appears right justified. Preceding zeroes are suppressed with the exception of the zero to the left of the decimal point.
Unit
– Weight unit displayed.
CR
– Carriage Return (0Dxh.)
LF

The terminal has not recognized the received command.
ET
– Transmission error
The terminal has received a “faulty” command, such as a parity error.
EL
– Logical error
The terminal cannot execute the received command.
CR
– Carriage return (0Dxh)
LF
– Line Feed (0Axh)
Comment
– the <CR> and <LF> characters will not be shown in this description.
Tips for the Programmer
Tips for creating a robust communication with the terminal using the SICS protocol include:
Command and Response
Improve the dependability of application software by having the program evaluate the response of the terminal to a command.The response is the acknowledgment that the terminal has received the command.
EN 102
Reset
7000 SERIES INDICATORS
When establishing communication between the terminal and system, send a reset command to the terminal to enable a start from a determined state. When the terminal or system is switched on or off, faulty characters can be received or sent.
Quotation Marks (“ ”)
Quotation marks included in the command responses are used to designate fields and will always be sent.
Commands and Responses MT-SICS Level 0
The terminal receives a command from the system computer and acknowledges the command with an appropriate response. The following sections contain a detailed description of the command set in alphabetical order with the associated responses. Commands and responses are terminated with <CR> and <LF>. These termination characters are not shown in the following description, but they must always be entered with commands or sent with responses.

C.3 Report
In order to print reports of the Alibi memory, totalization registers, target table (Checkweighing application), ID table
(Counting application), a connection must be made for the “Reports” function. When a reports connection is made to a serial port, whenever a report is run and then printed, it will be routed to the assigned port.
The line width of the printed report is selectable as either 40 characters or 80 characters in setup so that all reports have the same general format. These formats are fixed and cannot be changed. A header and a footer consisting of additional line feeds and the record separator character are also selected in the Reports sub-block of
Communications.
Samples of the Alibi memory and totalization register reports in a 40 column wide and an 80 column wide print are shown in the following sections. The remaining application specific reports are shown in the detailed Application chapter of this manual.
Alibi Memory
The alibi memory can be viewed and printed. Alibi memory is viewed by accessing the Operator menu (M key) and then selecting the ALIBI icon retrieved to a manageable level.
. A search screen is shown that can help reduce the number of records
After entering the desired search criteria, move focus to the START text and press ENTER. The Alibi memory report will be run and the first record will be shown on the display. Move through the results using the UP and
DOWN navigation keys. There is a scroll bar indicator on the right of the display to indicate where in the search results the currently displayed record is positioned.
Pressing PRINT with any record shown will initiate a transmission of the results out the port programmed as
Reports. Examples with two records are shown in Figure C-1 and Figure C-2.

C.4 Variable Access
All setup parameters and a few triggers and statuses in the terminal are available through a connection called
“Variable Access”. This is a serial interface assignment on COM1that permits remote clients to send and receive commands and data from the terminal.
Connection
In order to access the variables in the T72XW terminal, the COM1 port must be used and it must be assigned as
Variable Access in the connection menu of setup.
Make sure the serial port of the remote device matches the parameters selected for the COM1 port. This includes the baud rate, data bits, parity bit, and 1 stop bit.
Connect an RS-232 cable between the remote client PC and the COM1 port of the T72XW terminal.
Open a program to communicate with the terminal (such as HyperTerminal). Refer to the Commands section to understand how the commands should be structured.
Commands
The T72XW supports two commands - Read and Write. Some variables are read only and some can be both read and written. A response is always sent after a Read request or a Write command. If a valid format and variable are requested in a Read, Response 1 from below will be sent. If the format is incorrect or a bad variable name is requested, an error like Response 2 will be sent. A Write command will receive either an acknowledge (ASCII
<ACK> - 06xh) for an accepted command or a negative acknowledgement (ASCII <NAK> - 15xh) for an invalid command or data.
A Space character is required between the index number and data that is being sent. This characters is shown as
<SP> (20xh) in the examples. All commands and responses are terminated with a Carriage Return and a Line
Feed character. These characters are shown as <CR>< LF> (0Dxh, 0Axh).
Individual Variables
The PC program can connect with the T72XW terminal to read and write specific variables per the following examples. The list of index numbers is given in the next section.
Read request: R(index#)<CR><LF>
Read filter value: R129<CR><LF>
Response 1 (valid): R129<SP>1<CR><LF>
Read filter value: R1

APPENDIX D GEO CODES
The GEO code feature provided in the T72XW terminal permits calibration readjustment due to changes in elevation or latitude without reapplying test weights.
This adjustment assumes a previously accurate calibration was done with the GEO code set properly for that original location and that the GEO code for the new location can be accurately determined.
The procedure for using this feature is as follows.
Original Site Calibration
scale will be calibrated.
Enter that GEO value into the GEO code parameter in setup at Scale > Calibration.
Immediately after entering the GEO code, perform a zero and span adjustment using accurate test weights.
Exit the setup menu tree.
The scale can now be used in its new location.
New Site GEO Code Adjustment
When a terminal is to be reinstalled at a different geographic location, gravitational and altitude changes can be accounted for by following these steps. Note that this procedure is not necessary if an on-site recalibration is performed.
1
scale will be used.
3 Enter that GEO value into the GEO code parameter in Setup at Scale > Calibration.
4 Immediately after entering the GEO code, exit the setup menu tree.DO NOT perform a normal calibration.
5 The calibration has now been adjusted for the differences in gravity from the original site of calibration to the new site of use.
Using the GEO code value for calibration adjustment is not as accurate as re-applying certified test weights and re-calibrating the scale in a new location.
