Unpacking and Startup
Unpack the Scale
•DO NOT LIFT SCALE BY THE TOP
SPIDER OR SUB PLATFORM!
•Remove the molded foam top from
the carton. On 2 lb. and 5 lb. capacity
scales the platform is packaged on
top of this foam. Gently lift and
remove the stainless-steel platform
cover only.
•Remove any options which may be
packed with the scale.
•Carefully remove scale from the
packaging by grasping both sides of
the base.
Scale Setup
•Place the scale on a stable, level
surface for operation.
•Adjust the corner leveling feet until
the level bubble indicates the unit is
level.
•Firmly tighten hex jam nuts on the
leveling feet. (Any time the scale is
relocated, it should be leveled.)
•Remove the protective plastic wrap
from the platform and place the
platform on the spider.
•Plug the scale into 110/120 VAC
Scale Operation
•Press the ZERO button to zero the
scale
•Press the UNITS button to cycle
through units of measure
•Press the PRINT button to send scale
data to a printer or connected
software
•Press SAMPLE SET to Create a Piece
Weight and Count
•Press TARE or KEYPAD TARE to enter a
tare weight

Basic Counting Operation
✓If a container will be used to hold
items being counted, place it on
the platform.
✓Press the SAMPLE SET button,
press repeatedly to scroll to the
desired sample size. OR key in the
sample size and press ENTER
✓Place the sample quantity on the
scale platform all at once
✓Piece weight is calculated, and
count displayed. All the remaining
parts may now be added to the
scale and counted.

7600 Advanced Operation.
See the 7600 Technical Manual for detailed configuration and setup information
Advanced Counting Operations
•Auto Sample Update (In CAL 10, EnH 15 select YES and in CFG 50, YPR 57
select P Err or P Acc to enable.) After the initial sample and piece weight
calculation placing additional parts on the scale platform at a quantity less than the
original sample size results in the scale recalculating the piece weight resulting in a
higher % off accuracy or lower % of error.
•2 Step Counting (In CFG 50,2S 56 select YES to enable.) Press the
button and place a sample quantity of the items to be counted on the scale platform.
Key in the number of pieces and press the button. Piece weight is calculated, and
scale will display count.
•Counting with A Piece Weight and Tare Weight Press the button, key in the
piece weight and press the button. Press the button, key in the tare
weight and press the button OR place the empty container (or representative
container) on the scale platform and press the button. This information may
also be scanned into the scale with a barcode scanner and barcode that has the input
piece weight and input tare weight commands embedded.
•Negative Counting (In CFG 50,2S 56 select YES and nEG 59 select YES to
enable.) Negative counting allows a negative or count out of a full container. Place the
container and parts on the scale, press the button and remove a sample
quantity from the container. Key in the number of pieces and press the button.
Piece weight is calculated, and scale will display count removed as a negative number.
•Top End Counting (In CFG 50,2S 56 select YES and nEG 59 select No to
enable.) Top end counting is an easy way to determine the count of a container of parts
without having to remove them from the container. Place the container and parts on

•the scale, Press the button, key in the tare weight and press the button
and remove a sample quantity from the container. Key in the number of pieces and
press the button. Piece weight is calculated, and scale will display count of the
parts in the container.
•Auto Sample to Bulk (In CFG 50,ASb 58 select YES to enable.) This counting
method is designed for a two-scale base system. Sampling occurs on the light capacity
higher resolution scale base for improved piece weight calculation accuracy then
automatically switches to the second heavier capacity base for bulk counting.
•Product ID and Piece Weight Database Store and Recall (In CFG 10,Str 16 select
Ato enable.). Press the button, key in the product ID and press the button.
If this product ID is not in memory the scale will go to the piece weight calculation
function and display ADD XX. Perform a sample by scrolling to the desired sample size
and placing the parts on the scale platform. The scale will calculate the piece weight and
store it with the product ID in memory. Perform counting functions as needed for this
part. Repeat the above steps for each new product ID and piece weight to store in
memory. You can store a total of 250 pieces. To recall an ID and Piece Weight from
memory press the button, key in the product ID and press the button.
Product ID and piece weight will be loaded and scale will be in count mode ready to
count this part. This may also be configured to enter a piece weight instead of using the
sample process to establish a piece weight. In CFG 10,Str 16 select Bto enable.

Accumulation
•The accumulation function will keep a running total of what has been weighed or
counted. As an example, if you're weighing 10 boxes that each have a piece count of
100, the accumulation feature would allow you to see the total of 100 pieces for each
box and a total of 1000 pieces for all the boxes. Additionally, when using a printer in the
above scenario an individual box label showing a quantity of 100 and a pallet label
showing 10 boxes of 100 for a total of 1000. The 7600 can be set up for:
oManual Accumulation press the button to accumulate. In CAL 1, ACC
6,select Pri to enable manual accumulation of weight or CAL 1, ACC 6,
select Cnt to enable manual accumulation of count
oAuto Accumulation occurs on first stable non-zero weight. In CAL 1, ACC 6,
select A-Pri to enable auto accumulation of weight or CAL 1, ACC 6,
select A-Cnt to enable auto accumulation of count
•To clear the accumulation, register press and hold the button. The display will
flash CLr.ACC and nO. press the button to select YES and the button
to clear the accumulation totals.
•When using accumulation and with the optional printer the system can be configured to
print a box label and pallet label.
Setpoint Entry
•When the setpoint relay option is installed enter the setpoint values by pressing and
holding the button, keying in values and press the button
