INSTALLATION
Unpacking
Before beginning installation of your Digital Counting Scale, make certain the instrument has
been received in good condition. Carefully remove the instrument from the shipping carton and
inspect it for any evidence of damage (such as exterior dents or scratches) that may have taken
place during shipment. Keep the carton and packing material for return shipment if it should
become necessary. It is the responsibility of the purchaser to file all claims for any damages or
loss incurred during transit. Refer to the Counting Scale Unpacking and Re-Packing
Instructions, 8526-M246-01, for additional information.
Placement
Place the scale on a stable, vibration-free level surface away from direct sunlight and from any
rapidly moving air source (heating/cooling vents, fans, etc.). Make certain the power cord and
peripheral cables are routed out of the way of normal traffic.
CAUTION! DO NOT place the scale on any unstable cart, stand or table. The
scale may fall causing injury to the operator, and seriously damage the unit,
or proper operation of the scale may be inhibited.
Level Adjustment
Check to make certain the scale is level. The level indicator is located in the center of the
weighbridge under the Stainless Steel commodity tray. Remove the commodity tray and
observe the level bubble (see Figure No. 1). If the scale is not level (the bubble will not be
centered), loosen the locking nut on all four (4) mounting feet (see Figure No. 2) and adjust
them as required to center the bubble and attain a level scale. Once a level condition has
been obtained, lock the mounting feet in place by tightening the adjustment nuts against the
bottom of the scale.

PRECAUTIONS
Most scales are designed for an office type environment. The Digital Counting Scale is no
exception to that rule. Such an environment is free of excessive dust and moisture and provides
a comfortable temperature. In general, the scale will perform well over a temperature range of
32° to 104° F (0° to +40° C). In order to keep cooling requirements to a minimum, the scale
should be placed out of direct sunlight and to provide adequate air circulation, keep the area
around the scale clear. Make certain the scale is not directly in front of a heating or cooling vent.
Such a location will subject the scale to sudden temperature changes and air currents which may
result in unstable weight readings. Insure that the scale has good, clean AC power and is
properly grounded. In areas subject to lightning strikes, additional protection to minimize
lightning damage, such as surge suppressors, should be installed.
CAUTION! When in parallel runs, locate external Load Cell
cables a minimum of 24 inches away from all AC wiring.
5
INTERCONNECTIONS
Remote Scale Connection
If a remote scale is used, it connects to the counting scale via a 9-pin "D" connector (REMOTE
SCALE) located on the rear panel of the scale (see Figure No. 2). Before connecting your
remote scale to the counting scale, verify that your scale cable is correctly wired. Refer to Figure
No. 3 for pin identification of the remote scale connector.
The Digital Counting Scale ships from the factory configured for remote scales that do not use
load cells with sense leads (4 wire load cells). The sense jumpers, J1 and J2 are installed for
proper operation with 4 wire load cells. If your remote scale uses load cells with sense leads (6
wire load cells), jumpers J1 and J2, located on the printed circuit board (see Figure No. 5) should
be placed on one pin only or disconnected.
Make certain that the connector retaining screws are used to hold the remote scale cable
connector securely to the rear panel.

RESET FUNCTION
A hidden key (under the Cardinal bird emblem) is provided to be used as an reset function to
abort the current operation and return the scale to the weight display mode. This allows the
operator to start the operation again from the beginning.
Figure No. 6
ANNUNCIATORS
The annunciators are turned on to indicate that the scale is in the mode corresponding to the
annunciator label or that the status indicated by the label is active. It will be helpful to refer to
the scale keyboard or Figure No. 6 when reading this section. The following describes the
functions of each annunciators.
GROSS
The GROSS annunciator is turned on to show that the weight displayed is the gross weight.
Gross weight may be displayed only when in the weight mode and a zero tare weight (or no tare
weight) value is stored. Note that the GROSS annunciator is only active when the display is in
the weight mode as shown by the illumination of the lb or kg annunciator.
TARE
The TARE annunciator is turned on to show that the scale is in a weight mode in which a known
tare (container) weight may be keyed in via the numeric keypad, or in a mode that will display the
current TARE weight.
NET
The NET annunciator is turned on to show that the weight displayed is the net weight. Net weight
is determined by subtracting the stored tare weight from the gross or scale weight. The tare
weight, usually the weight of the container, is entered using the tare key. Note that the NET
annunciator is only active when a zero tare weight or tare weight value is stored and the display
is in the weight mode as shown by the illumination of the lb or kg annunciator.
kg
The kg annunciator is turned on to show that the weight displayed is in kilograms. The lb/kg key
may be used to select kilogram as the weighing units.
lb
The lb annunciator is turned on to show that the weight displayed is in pounds. The lb/kg key
may be used to select pounds as the weighing units.
ZERO
The ZERO annunciator is turned on to show that the scale gross weight is within ± ¼ of a
division of true zero (center-of-zero).
10
ANNUNCIATORS, Cont.
MOTION
The MOTION annunciator shows that the scale weight is unstable. An unstable weight reading
may be caused by motion on the scale platform. Accumulation of piece counts, Zero and printing
cannot take place when the MOTION annunciator is illuminated.
ID
The ID annunciator is used to show the status of the Identification Number mode. During
operation, the ID annunciator will be ON (not flashing) to indicate that an ID number is active.
When the scale is in the ID ADD, EDIT or DELETE modes of operation, the ID annunciator will
be flashing.
ACCUM
The ACCUM annunciator shows that the display is in the Accumulator mode and that the value
displayed is the current contents of the accumulator. Individual counts are adjusted via the ( + )
and ( - ) keys or optionally, any count may be entered using the numeric keypad. Note, a flashing
ACCUM annunciator indicates that the current count has been added to the accumulator (count
annunciator is also lit).
SAMPLE
The SAMPLE annunciator shows that the display is in the Sample mode and that the value
displayed is the sample quantity requested in pieces.
COUNT
The COUNT annunciator shows that the display is in the Count mode and the value displayed is
the count quantity of either the pieces removed from the scale platform (reverse counting) or the
number of pieces added to the scale platform (normal counting). The count value is determined
by dividing the net or gross weight (as selected) by the average piece weight.
INSUFFICIENT SAMPLE
The INSUFFICIENT SAMPLE annunciator is located between the display and the numeric
keypad and shows that the sample selected is too small to calculate an accurate piece weight. If
a counting function is continued by pressing the COUNT key a second time without increasing
the sample size, the INSUFFICIENT SAMPLE annunciator will flash. Note that increasing the
sample size by the amount indicated prior to pressing the COUNT key a second time, will turn off
the INSUFFICIENT SAMPLE annunciator and result in an accurate piece weight.
BATTERY LOW
The BATTERY LOW annunciator is used with the battery operation and will flash slowly to
indicate that the internal battery requires charging. If continued use furthers drains the battery,
the annunciator will stop flashing and stay on continuously. No change in operation will occur
until just before the battery voltage drops to a level where operation is affected. At this level, the
scale will automatically turn itself off. Note that when the scale is charging the battery,
BATTERY LOW annunciator will flash until charging has been completed.
REMOTE SCALE
The REMOTE SCALE annunciator is illuminated when the optional remote scale platform has
been selected for use. The remote scale is selected by pressing the REMOTE SCALE key.
POWER ON
The Power Switch is located on the right side panel towards the front of the scale. Place the
power switch in the on position. The scale will perform a brief lamp test. This test consists of
illuminating all display segments and annunciator LED's for approximately three (3) seconds to
allow the operator to make a visual verification that the display is operational. After completion
of the lamp test, the scale will display the model number and software revision level, then the
weight display will show zero weight, indicating the scale is ready for use.

Automatic Average Piece Weight Re-Computation
Immediately after a standard sampling operation, if a quantity of pieces, less than the original
sample size is added to the scale platform, a new average piece weight will be calculated
automatically. This new average piece weight is based on a larger sample than that used initially
therefore improving the accuracy of the count.
NOTE: The automatic recomputation of the average piece weight occurs only once for each new
sample. Note also that the recalculation of the average piece weight will not take place if the
quantity of pieces added is equal to or greater than the original sample quantity, nor will it take
place if the display mode is changed before the pieces are added.

OPERATION USING ID(S)
This section describes the various operating procedures of the Digital Counting scale using the
ID mode. The ID (identification number) function may be thought as a catalog of stored values for
up to 300 separately identifiable counting operations. Those values, stored under an assigned ID
number, are: the TARE WEIGHT1 (if used), the UNITS (Average Piece Weight) and the
ACCUMULATED COUNT of a counting operation. They are accessed by entering the assigned
ID number.
1
A TARE WEIGHT value can be stored for both the Local and Remote scale, allowing the
operator to use a small container for the sample and a pallet, tote or the shipping box for the
final item count. If required, the stored Tare weight value for an ID can be added or updated
before or during a Count or Sample operation.

OPERATION USING ID(S), Cont.
Operation With Stored Tare Weight Values
The Digital Counting Scale can store separate Tare weight values for each ID for both the Local
and Remote scale. This allows the operator to use a smalll container for sampling and a larger
container such as a pallet, tote or the shipping box for the final item count.
The TARE WEIGHT value can be programmed (stored) when first adding an ID or it can be
added to the ID before or during a Count or Sample operation. Note, that if an ID has a stored
Tare weight value and the Tare weight is updated during a Count or Sample operation, the
updated value will become the stored Tare Weight value.
NOTE: When an ID is selected that has a stored Tare weight, the scale will
automatically switch to the Net mode operation when the SAMPLE key or the COUNT
key is pressed and display a negative weight (the Tare) if the container is not on the
scale.

Automatic Average Piece Weight Re-Computation
Immediately after a standard sampling operation, if a quantity of pieces less than the original
sample size is added to the scale platform, a new average piece weight will be calculated
automatically. This new average piece weight is based on a larger sample than that used initially
therefore improving the accuracy of the count.
NOTE: The automatic recomputation of the average piece weight occurs only once for each new
sample. Note also that the recalculation of the average piece weight will not take place if the
quantity of pieces added is equal to or greater than the original sample quantity, neither will it
take place if the display mode is changed before the pieces are added.

CALIBRATION and SETUP
This scale was calibrated at the factory and should not require adjustment. In the event that the
scale should need recalibration, the following describes the Calibration of the Digital Counting
Scale. A qualified technician should perform this function to maintain the instrument's high
degree of accuracy.
Before beginning calibration, the following equipment is required:
Calibrated test weights (Full capacity for all models, e.g. 5 lbs for 5 lb, . . . 100 lbs for 100 lb)
Small Flat Blade screwdriver (to remove calibration sealing screw)
If sealing wires require breaking for purposes of calibration, proper procedures under
National Institue of Standards and Technology Handbook 44 must be adhered to.
Calibration Sealing Screw

CALIBRATION PROCEDURE - LOCAL SCALE
1. With the scale power off, remove the calibration sealing screw on the right side panel, see
Figure No.7.
2. With the screw removed, place the power switch in the ON position. The scale will perform a
brief lamp test. This test consists of illuminating all display segments and annunciator LED's
for approximately three (3) seconds to allow the operator to make a visual verification that
the display is operational. After completion of the lamp test, the scale will display the model
number and software revision level, then the weight display will change to SCALE.
SCALE
3. Select the LOCAL scale by pressing the LOCAL SCALE key.
4. The weight display will change to LOAD and the count display will change to xxxxxx. Note
that xxxxxx is the capacity of the scale and the load required to calibrate the scale. This will

SAMPLING AND COUNT ACCURACY
This section describes certain conditions that determine the accuracy of a parts counting
operation and procedures you can follow to assure optimum performance of your Digital
Counting Scale. Accurate counts depend upon the following conditions:
Functional accuracy of the scale.
Individual part weight variance.
Determination of parts sampling quantities.
Variance of container weights in tare operations.
ACCURACY OF THE SCALE (Refer to Figure No. 9)
TYPICAL CONDITION ACCURACY - on a stable surface, applied load less than 70% of scale
capacity, with no air currents or vibrations present, using parts with weight variance less than
1%; the total weight of all parts in the sample must be:
0.2% (1/500) of scale capacity for 99.5% accuracy
0.1% (1/1000) of scale capacity for 99% accuracy.
WORST CASE ACCURACY - on an unstable surface, applied load near 100% of scale capacity,
with air currents or vibrations present, using parts with weight variance less than 1%; the total
weight of all parts in the sample must be:
0.5% (1/200) of scale capacity for 99.5% accuracy
Counting accuracy will be greater than 99.5% when the total weight of all parts in the sample
exceeds 0.5% of scale capacity.

SAMPLING AND COUNT ACCURACY, Cont.
INDIVIDUAL PART WEIGHT VARIANCE
For a given sample quantity, as the total weight of all parts in the sample increases, the average
per-piece weight of the sample used becomes representative of the average per-piece weight of
the group of parts to be counted. The errors caused by part weight variance are reduced with
larger sample quantities. With knowledge of the typical percentage of variartion in per-part
weight of items to be counted, refer to the graph in Figure No. 10 to determine the sample
quantity needed to obtain a desired percentage of counting accuracy.
NOTES:
As your need for counting accuracy increases, the size of your samples must
also increase.
As individual uniformity of your parts decreases, sample size must increase.
Manual counting errors may occur if samples larger than necessary are used.
Because of variation of individual container weights, be certain to "tare off" each
container by placing the empty container on the scale and pressing the ZERO
key before proceeding with the count operation.

OPTIONAL BATTERY PACK OPERATION
The Digital Counting Scale can operate from a readily available Sealed Lead-Acid Camcorder
type battery (not included). If you wish to operate the scale from a battery, you must first obtain
and install a CAM-350 Type 12 volt 2000 mAh (2.0 Ah) battery before operations can begin. The
battery is contained inside the instrument and is easy to install. Access is via a removable panel
on the right side of the scale (See Figure No. 11). The scale will operate with a "fully charged"
battery for approximately ten (10) hours and is easily recharged with the scale's built-in charger.
NOTE: The battery can be purchased from the Cardinal Scale Parts Department
(p/n 6800-0018) or ordered from the following companies online:
www. planetbattery.com
www.ebatts.com

OPTIONAL BATTERY PACK OPERATION, Cont.
Discharging the Battery Pack
The battery pack is discharging when the scale is operated without the AC power cord plugged
into a wall outlet. The Battery Low annunciator on the scale keypad serves to indcate the state of
the battery pack.
When the scale is operating by battery power, and the battery pack has sufficient charge to
power the scale, the Battery Low annunciator is off. If the battery becomes discharged while the
scale is in use, the Battery Low annunciator will flash slowly to indicate the battery pack needs to
be charged. When this occurs, the battery pack will have sufficient charge to power the scale for
a short time, approximately (5) five minutes. If continued use further drains the battery pack, the
Battery Low annunciator will stop flashing and stay on until the battery pack becomes severely
discharged. When the battery pack is unable to power the scale, the scale will turn off
automatically to prevent damaging the battery.
Due to the nature of batteries, shutting the scale off will cause the battery pack to recover
slightly. If the scale is operated after turning itself off, it may run for a few minutes before the
Battery Low annunciator begins to flash again. If the battery pack is too discharged to power the
scale, it will not power up when the power switch is place in the ON position, but will illuminate
the Battery Low annunciator for one minute to show the operator that a charge is needed before
operations can continue.
If the battery pack has become severely discharged, the scale may not respond at all when
turned on. This is a safety feature to prevent the scale from being powered up when the battery
voltage is excessively low. Plug the scale into the AC wall outlet to charge the battery pack.
Charging the Battery Pack
The battery pack can be recharged with the built-in charger in the scale. The charger in the scale
is a dual-level float charger. The first level does most of the charging rapidly, while the second
level adds the remaining charge gradually. This type of charge profile greatly prolongs the life of
the battery pack. Due to the sophisticated nature of the charger the battery pack can be left
connected to the charge indefintely, without risk of damage.
When the battery pack installed in a scale needs to be charged, simply plug the AC power cord
into a wall outlet and charging will begin. Note that operating the scale during charging only
minimally affects the charge time of the battery pack. The scale can operate at a 100% duty
cycle and will only prolong the charge time by less than 20%. Note too that charge time is
dependent on the depth of the discharge and will vary from one application to the next, but will
typically not exceed 10 hours even with the scale turned on.
While the battery pack is charging, the Battery Low annunciator will flash. It will continue to flash
until the battery is fully charged. Upon reaching full charge, the annunciator will turn off. This
gives the operator a visible indication of the charging status of the battery. Note that the Battery
Low annunciator is only on when the scale is on. If the battery pack is charged with the scale off,
the scale must be turned on to determine status of the battery.
35
OPTIONAL BATTERY PACK OPERATION, Cont.
Optimum Battery Pack Performance
The life of the battery pack depends greatly on the duty cycle of the scale, depth of discharge
and operating temperature. The battery pack will normally provide eight (8) hours of continuous
operation over an operating range of 14° to 104° F (-10° to +40° C). Several steps can be taken
to optimize the performance and life of the battery pack.
1. Enable the Auto Shut-Off feature of the scale by entering a 1 (YES) when the scale
prompts for Auto Off during Setup. (Refer to the Setup and Calibration section for an
explanation of the setup feature). This selection will cause the scale to shut itself off after
the period of inactivity selected in setup, thus preserving the battery pack.
2. If possible, plug the AC power cord into a wall outlet after each work shift to allow the
battery pack to recharge. This will minimize the depth of discharge and greatly increase
the number of cycles the battery pack can undergo.
3. If conditions permit, avoid charging and discharging the battery pack in extreme cold. Due
to the chemistry of batteries, low temperatures decrease the capacity of the battery pack
significantly causing a greater depth of discharge at colder temperatures than at room
temperature. The battery pack will function without problems at temperatures as low as
14° F (-10° C) but will not last as many cycles as it would at room temperature.
4. Avoid storing the battery pack after discharging. If the battery pack is to be left for several
days or more, make certain that it is charged before storage. The optimum environment
for batteries is to charge while stored. The type of charger used in the scale will not
damage batteries in any way even if the battery pack is left charging indefinitely.
