Preface
Thank you for purchasing of our CAS scale.
This scale has been designed with CAS reliability, under rigid quality control
and with outstanding performance.
Your departments can enjoy with this high quality reliable CAS product.
We believe that your needs will be satisfied and you will have proper reliability
with in variable weight.
This manual will help you with proper operations and care of the CT100 series.
Please keep it handy for the future references.
Precautions
To ensure that you get the most from your scale, please follow these
instructions.
1. Do not disassemble the scale. When any damage or defect occurs, contact your
CAS authorized dealer immediately for proper repair.
2. Do not overload beyond the maximum weight limit.
3. Scale must be grounded to minimize electricity static. This will minimize defect or
electric shock.
4. Do not pull the plug by its cord when unplugging. Damaged cord could cause
electric shock or fire.
5. To prevent from fire occurring. Do not place or use the scale near flammable or
corrosive gas.
6. To reduce electric shock or incorrect reading. Do not spill water on the scale or
place it in humid condition.
7. Avoid placing the scale near heater or in direct sunlight.
8. Insert plug firmly to wall outlet to prevent electric shock.
Make sure to plug your scale into the proper power outlet. For maximum
performance, plug into a power outlet 30 minutes before the usage for
warm up.
9. For consistent and accurate reading, maintain periodical check by your CAS
authorized dealer.
10. Avoid sudden shock to the scale. Internal mechanism could be damaged.
11. Grab on the bottom of the scale when moving. Do not hold by the platter.
12. Place the scale on firm and temperature consistent environment.

4
13. If the scale is not properly level, please adjust the 4 legs at the bottom of the
scale (turn legs clockwise or counterclockwise) so as to center the bubble of the
leveling gauge inside the indicated circle.
14. Keep the scale away from other electromagnetic generating devices. This may
interfere with accurate reading.

Calibration

Chapter 2. Calibration
This chapter explains how to set in calibration mode.
To go to calibration mode, turn on the power while pressing the calibration switch.
Calibration mode is comprised of the following menus.
Table 1: Calibration Mode
Menus Description Remarks
CAL  Make calibration save
EEPROM
SPAN  Make fine calibration
CSET1

Set part 1, such as lb/kg, capacity, e value,
dual/single, weight unit, maximum tare, initial
zero, and one-time tare/successive tare,
Minimum Weight Sale Enable/Disable,
Stable Sensitivity.
save
EEPROM
CSET2

Set part 2, such as digits, comma/dot, local
gravity, destination gravity, password, round
and print enable/disable.
save
EEPROM
MAC
 Set MAC address (Ethernet version)
TEST

Test device’s status, such ad, span, display,
key, memory, print and battery
PLANT

Make factory setting, such as scale default set
and erase all data
A. CAL
① Initial display in calibration mode.
② Press key. You will see the “UnLoad” on the display.
Calibration Range A/D Value : (Load – Unload ) > 5000

12
B. SPAN
* And then, it goes to “Fine Calibration” mode.
In this mode you can use the '4' key to decrease the value of the both calibration
constants at the same time and '5' key to decrease them. That makes the offset on
the SPAN value.
Use '7' key to decrease the value of second calibration constant only and key '8' to
increase it.
That makes the proportional change of the value.
If A is the first calibration constant and B is the second the formula is:
internal = A + B*X
where X is the row ADC value..
③ press key again. The machine finished Zero
adjustment. And then it beeps and saves the value. The
display will show “LoAd” message and the value of “Load A/D”.
① Press to move to SPAN calibration mode. And then
Press key. The display shows ADC value in internal
resolution (0~60000)
on XXXXX.
④ Place full capacity on the platter.
Press key. If the value of A/D remains stable for a while
the display will be shown “CAL” with beep.
