1.0 INTRODUCTION
•
The CBW series of scales provide an accurate, fast and versatile series of general purpose weighing scales with counting, % weighing and check-weighing functions.
•
There are 2 series of scales - CBW scales which use kilograms as the default unit and the CBWa range of scales have changeable units from pounds to kilograms. The scales in these series share the same functions except the CBWa series have the ability to change the weighing units.
•
There are 5 models in each series with capacities up to 45 kg /
100 lb.
•
These all have stainless steel weighing platforms on an ABS base assembly.
•
All scales have sealed keypads with colour coded membrane switches and the displays are large easy to read liquid crystal type displays (LCD). The LCD’s are supplied with a backlight.
•
The scales include automatic zero tracking, audible alarm for preset weights, automatic tare, pre-set tare, an accumulation facility that allows the count to be stored and recalled as an accumulated total and bi-directional RS-232 interface for communicating with a
PC or printer.

3.2 INSTALLATION OF CBW SERIES
•
The CBW Series comes with a stainless steel platform packed separately.
•
Place the platform in the locating holes on the top cover.
•
Do not press with excessive force as this could damage the load cell inside.
•
Level the scale by adjusting the four feet. The scale should be adjusted such that the bubble in the spirit level is in the centre of the level and the scale is supported by all four feet.
•
Attach the power supply cable to the connector on the bottom of the scale. Plug in the power supply module. The power switch is located on the base on the right side of the scale.
•
The scale will first display the model number (CBW 30- where 30 denotes the capacity of the scale in kg), followed by the revision numbers (1.2-2.03 where 1.2 is the current hardware revision number of the main circuit board and 2.03 is the current software revision number). A self-test is followed next. At the end of the self-test it will display “ZERO”, if the zero condition has been achieved. A stable symbol and “GROSS” indicators are also displayed.
4.0 KEY DESCRIPTIONS
KEYS PRIMARY FUNCTION
[Zero] Sets the zero point for all subsequent weighing. The display shows zero.
[Tare]
It tares the scale and stores the current weight in memory as a tare value, subtracts the tare value from the weight and shows the results. This is the net weight. Entering a value using the keypad will store that value as the tare value.
SECONDARY FUNCTION
or [Enter] key when setting parameters or other functions.
A secondary function is available to increment the active digit when setting a value for parameters or other functions.
© Adam Equipment Company 2004

[Limit]
It sets the limits for check weighing and allows setting of either the low limit or the high limit or both.
[%]
It enters the percent weighing
[Func]
[Print]
[Units]
function. Allows the weight, unit weight, and count to be seen when parts counting.
This is used to select the function of the scale. When the scale is weighing, it will select parts counting. When it is not in the weighing mode it will return the user to weighing.
It is used to print the results to a PC or printer using the optional RS-232 interface. It also adds the value to the accumulation memory if the accumulation function is not automatic.
It is used to change the weighing units of the display from kilograms to grams and back to kilograms for CBW series.
For CBWa scales this key will select kilograms, grams,
Pounds and Pounds/ounces for the weighing unit, if enabled. This should only be done in gross weighing or at zero.
A secondary function is available to move the active digit to the right when setting values for parameters or other functions.
A secondary function is available to move the active digit to the left when setting values for parameters or other functions.
A secondary function [C] is available to act as a clear key when setting values for parameters or other functions.
A secondary function [ESC] is used to return to normal operation when the scale is in a parameter setting mode.

5.0 DISPLAYS
The LCD display will show a value and a unit to the right of the digits.
(Stable) and (Low battery).
6.0
OPERATION
6.1 ZEROING THE DISPLAY
•
You can press the [Zero/Enter] key at any time to set the zero point from which all other weighing and counting is measured.
This will usually be necessary when the platform is empty. When the zero point is obtained the display will show the indicator for
“ZERO”.
•
The scale has an automatic re-zeroing function to account for minor drifting or accumulation of material on the platform.
However you may need to press the [Zero/Enter] key to re-zero the scale if small amounts of weight are still shown when the platform is empty.
© Adam Equipment Company 2004
8
6.2 TARING
•
Zero the scale by pressing the [Zero/Enter] key, if necessary. The zero indicator will be on. Place a container on the platform, a value for its weight will be displayed.
•
Press the [Tare] key to tare the scale. The weight that was displayed is stored as the tare value and it is subtracted from the display, leaving zero on the display. The "TARE" indicator will be on and the “GROSS” indicator will be off. As product is added only the weight of the product will be shown. The scale could be tared a second time if another type of product was to be added to the first one. Again only the weight that is added after taring will be displayed.
•
When the container is removed a negative value will be shown. If the scale was tared just before removing the container, this value is the gross weight of the container plus all products those were removed. The “ZERO”- indicator will also be on because the platform is back to the same condition it was when the [Zero/Enter] key was last pressed.
6.3 WEIGHING A SAMPLE
•
To determine the weight of a sample, first tare an empty container if used, then place the sample in the container. The display will show the weight and the units of weight currently in use.
6.4 PERCENT WEIGHING
•
The scale will allow a sample weight to be shown as 100%. Then any other weight placed on the scale will be displayed as a percentage of the original sample. For example is 350g is placed on the scale and the [%] key is pressed the display will show
100.00%. Remove the 350g weight and place a 300g weight on the scale. The display will show 85.71% as 300g is 85.71% of 350g.
•
NOTE: The scale may jump by large numbers unexpectedly if small weights are used to set the 100% level. For example, if only 23.5g is placed on a scale with 0.5g increments and the scale is set to
100%, the display will show 100.00%, however a small change of weight will cause the display to jump to 102.13% as one scale division (0.5g) increase to 24.0g will be equivalent to an increase of
2.13%.
•
Pressing [Func] will return the scale to weighing.

6.5 PARTS COUNTING
•
Before beginning, tare the weight of any container that will be used, leaving the empty container on the scale.
•
Press the [Func] key to begin. The scale will show " " asking for a sample size of 10 parts. Change the sample size by pressing the [Tare/ ] key. The display will cycle through the options: 10, 20, 50, 100, 200 and back to 10.
•
Place the number of samples on the scale. The number should match the options for parts counting, i.e., 10, 20, 50, 100 or 200 pieces.
•
Press the [Zero/Enter] key when the number matches the number of parts used for the sample. As more weight is added, the display will show the number of parts (pcs).
•
Press the [%] key to display unit weight (g/pcs or lb/pcs), Total weight (kg or lb) or the count (pcs).
•
Press [Func] to return to normal weighing.
•
‘lb’ will be shown on the CBWa scales when weighing unit is set to pounds.
6.6 CHECK-WEIGHING
Check-weighing is a procedure to cause an alarm to sound when the weight on the scale meets or exceeds the values stored in memory.
The memory holds values for a high limit and a low limit. Either or both the limits can be used.
6.6.1 Setting up Check-weighing while weighing
•
Press the [Limit] key. The display will show the current High Limit with the left most digit flashing and the HI symbol on the left of the display.
•
To change the value shown press [%/ ] and to select the digit to change press [Limit/ ]. Use [Tare/ ] to increment the flashing digit. When the desired value is shown press [Zero/Enter] to accept the value. If you want to reset the value to zero, press the
[Func/C] key to clear the value.
•
After pressing the [Zero/Enter] key the display will then show the
Low Limit, the “LO” symbol will be on to the left side of the display. Enter the low limit in the same way the high limit was entered.

•
The limits are displayed in Kg.
•
Pressing the [Zero/Enter] key will return the scale to weighing, with the Check-weighing function enabled.
•
When a weight is placed on the scale the arrows will show whether the weight is above or below the limits and the beeper will sound as described below.
BOTH LIMITS SET
The display will show OK and the beeper will sound when the weight is between the limits.
LOW LIMIT SET HIGH LIMIT is set to zero.
The display will show OK and the beeper will sound when the weight is less than the Low
Limit. Above the Low Limit the display will

HIGH show HI and the beeper will be off.
LOW LIMIT is set to zero.
The display will show LO and the beeper will be off when the weight is less than the High
Limit. Above the High Limit the display will show OK and the beeper will be on.
The beeper will never sound and the display will show LO if the weight is less that the Low
Limit and HI if the weight is greater than the
Low Limit.
6.6.2 Setting up Checkweighing while Parts Counting
•
Checkweighing facility can be set up for Parts Counting by entering values as Low and High Limits to be keyed in by the user. The limits are displayed in PCS.

•
See Section 7 on PARAMETERS for details. The accumulation function is only available when weighing. It is disabled during percent weighing or parts counting.
•
The accumulated weights will be stored in the master unit of the scale, i.e. kg or lbs.
•
If at any time the weighing units are changed, the accumulated data will be lost.
6.8 MANUAL ACCUMULATION
•
When the scale is set to manual accumulation the weight displayed will be stored in memory when the [Print] key is pressed and the weight is stable.
•
The display will show " " and then the total in memory for 2 seconds before returning to normal. If the optional RS-232 interface is installed the weight will be output to a printer or PC.
•
Remove the weight, allowing the scale to return to zero and put a second weight on. Press [Print], the display will show " " and then show the new total.
•
Continue until all weights have been added.
•
To view the total in memory press the [Print] key when the scale is at zero. The display will show the total number of items "
" and the total weight before returning to zero. The total will also be printed via the RS-232 interface.
•

10.0 CALIBRATION
•
The CBW scales are calibrated using metric weights and the
CBWa scales can be calibrated using either metric or pound weights, depending on the weighing unit in use before calibration.
•
To start calibration turn the scale off and then turn it on again.
Press the [Tare] and [%] keys together once, during the initial counting from 9 to 0 on the display.
•
The display will show " ". Remove all weight from the pan and then press the [Zero/Enter] key to set the initial zero point when the scale is stable.
•
The display will then show “ ” at which point the calibration mass should be placed on the pan. It is best to use a weight close to the full capacity of the scale.
•
Press the [Zero/Enter] key. The display will then show the last mass used. If this is the same as the mass on the pan then this can be used or a different value can be entered.
•
To use this value, press the [Zero/Enter] key when the stable indicator is on.
•
Or if a different value is desired, enter the value using the [ ] arrow key to select the flashing digit and the [ ] to increment the flashing digit. If value is correct, press the [Zero/Enter] key to accept when the stable indicator is on.
•
Remove the calibration weight as the scale counts back from 9 to
0.
•
If an error message “ ” or “ ” is shown during calibration, re-check the calibration and repeat, if necessary. If the error cannot be corrected contact your dealer or Adam Equipment for advice.
CBCa Scales only:
CBWa scales will also have the Lb or Kg (or g) indicator on to show the unit of the weight requested. If the scale was in pounds before starting the calibration, the weights requested will be in pound values. If the scale was weighing in kilograms then metric weights will be requested.
