Calibration
The calibration function can auto-detect any calibration weight in multiples of
100g, i.e., 200g, 500g, 1000g, etc., as long as the weight does not exceed the
maximum capacity of the balance. Use a calibration weight of at least 20% of the
total capacity of the scale (eg. 6kg for a 30kg capacity counting scale.
NOTE: The counting scale is calibrated at the factory and can be used out of the
box. It should be calibrated one time per year.
Quickly press ZERO three times. “AU-CAL” will be displayed on the lower right
corner of the screen.
Place no less than 20% of the full range of weights on the weighing pan.
The instrument will be calibrated.
Calibrate the instrument using any available reference weights.
The instrument can only be as accurate as the standard masses used.

Counting Function
WT/SET
Enter the unit weight with the number keys and press WT/SET.
When more units are added, the counting window will show the total number
of pieces.
The total weight window will display the total sample weight.
The unit weight window will display the weight of a single unit.
Press CE to cancel the WT/SET setting.
PCS/SET
This counting function is used to count the number of parts by extrapolating
values from the original sample.
Place the sample on the scale.
Input the number of pieces in the sample by using the numerical keys (use at
least 10pcs). Press PCS/SET to confirm.
As more units are added, the counting window will show the amount of units.
The total weight window will display the total sample weight.
The unit weight window will display the weight of a single unit.
NOTE:Use larger initial samples for more accurate results:
Pcs. Weight <0.3g = Not Accurate.
Pcs. Weight 0.3g-0.5g = Use 50+ pcs sample for counting function.
Pcs. Weight: >0.5g = Use 10+ pcs sample for counting function.

Use M+ to find the cumulative weight and piece count of samples. For
example, place a sample of 100 pcs (2kg) on the scale. Press M+ and remove
the sample. Add 50 pcs (1kg), weigh, and remove. Press M+ and the total
count (150 pcs) and weight (3kg) will be displayed.
Place the first sample on the weighing pan.
Once the weight is shown, press M+.
Remove the first sample from the weighing pan. The display will return to “0.”
Place the second sample on the weighing pan.
Press M+ again.
Remove the second sample from the pan. The display will return to “0.”
Repeat this step for each sample.
Once all samples have been weighed and removed, press M+, and the entire
weight and count will be displayed.
Press MC to clear all data.

Checkweighing/Alarm
Press Alarm.
The screen will display 0.0kg in the top box and L in-hi in the lower.
If you would like to set upper and lower boundaries for pieces, rather than
weight, press ZERO to toggle between the settings.
Enter the upper bound for weight and press Alarm to confirm.
The scale will display L in-Lo.
Enter the upper bound for weight and press Alarm to confirm.
If you place something on the scale outside of the range it will flash either LO
or HI.
To cancel the alarm, go back through the settings and press CE for both the
upper and lower bounds.
The Checkweighing/Alarm function is used to signal upper and lower limits for
count and weight.
NOTE: The scale displays 'kg" each time. The alarm is however for whichever unit
was last used. For example, if you had been using grams before pressing Alarm,
the check weighing mode is for grams (even though it shows kg.

Connecting the balance to a PC requires an RS232 to USB adapter serial cable (not
included) and COMToo[BE1] l. COMTool is a serial communication terminal
program that can transmit bytes to and from devices connected to the PC’s COM
port.
RS232 Printout Settings
Connect the balance to the PC using the RS232 cable.
Open COMTool and select the COM port.
Set the baud rate to 9600.
Select serial input R.
Short press the CAL/PCS button to send data to the PC.

"1" corresponds to manual print mode. Under this setting, simply press "P"
to print.
"2" corresponds to stable print mode. Under this setting, the scale will print
once the weight is stable.
"3" corresponds to continuous print mode. Under this setting, the scale will
print continuously.
After choosing output mode, press ALARM to confirm.
Turn the scale off and the on.

Troubleshooting
12
If these troubleshooting measures do not solve the problem, contact customer
support. The balance should be serviced by authorized technicians only.

Factory Testing
Testing is performed to verify that the margin of error is less than .03g for a .01g
balance.
Margin of Error
Your balance has undergone extensive quality control (QC) testing at the
laboratory prior to shipment. The following QC tests have been conducted:
This testing is conducted with 4 different weights measured 4 times. For example,
for a 1000g maximum-capacity balance, linearity testing will be conducted with
weights of 200g, 500g, 800g, and 1000g. Larger capacity scales are tested with
more weights and more repetitions of testing. Testing is conducted until the
readings are consistent and accurate.
Linearity
A weight representing the maximum capacity of the balance is weighed 10 times
until the margin of error for each weighing is less than the acceptable specified
margin of error, i.e., less than .03g for a .01g accuracy balance. As an example, for
a 2000g maximum capacity balance, a 2000g weight is used. In order to pass the
repeatability test, each reading must fall within 1999.97g and 2000.03g.
Repeatability
Four points testing is conducted by placing a weight on each of corner of the pan
consecutively (not at the same time) and taking a reading each time. Each reading
should fall within the accepted margin of error to pass the test.
