1. Proper Operation / Introduction

1.1. 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.

WE hope that your departments enjoy with high quality of CAS product.

This manual will help you with proper operations and care of the PB(Portable Bench).

Please keep it handy for the future references.

1.2. Precaution • Make sure that you plug your scale into the proper power outlet.

• Place the scale on a flat and stable surface.

• Plug into a power outlet 30 minutes before operations.

• Keep the scale away from strong EMI noises may cause incorrect weight readings.

• This scale must be installed in a dry and liquid free environment.

• Do not subject the scale to sudden temperature changes.

• Do not subject the platter to sudden shocks.

• 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.

2)A Vibration or wind is exist

around The Scale.

- Check a foot. (Foots are must

all touched in flat part.)

-Check a PCB’s field ground.

(Field ground is must connected

to platform.)

ERROR 1(initial zero) 1)The Scale is not operate

6.2. Error Message

ERROR LIST REASONS SOLUTION

"Err 0" The "Err 0" occurs when scale is not stable. Remove unstable facts.

"Err 1" The "Err 1" occurs when a current zero point has shifted from the last span calibration.

Please call your CAS dealer.

"Err 2" The "Err 2" is not a real error. Only it prompts return CAL switch to the normal position.

Please call your CAS dealer.

"Err 3" The "Err 3" is an overload error. Please remove the weight.

"Err 9"

The "Err 9" is no weight error. When scale is in counting mode, you must load the weight.

If you have no weight on your scale, you can see this error message.

Please load the weight on your tray.

“Err 11”

The "Err 11" means a writing error of the internal nonvolatile memory. To recognize this error, be sure to check the voltage on the circuit and do calibration procedures.

If it still has "Err 11", replace the digital module.

“Err 12” The "Err 12" warns that the scale has lost the parameters for weighing regulations or has lost the factors for a digital span calculation.

Enter each condition codes again.

Please try a span calibration again if still not fixed.

“Err 14” The "Err 14" means calibration range is not correct. Please call your CAS dealer.
