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 en oy 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 sub ect the scale to sudden temperature changes.
• Do not sub ect the platter to sudden shocks.
• If the scale is not properly level, please ad ust 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.

"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 C S dealer.
"Err 2"
The "Err 2" is not a real error. Only it
prompts return C L switch to the
normal position.
Please call your C S 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 C S dealer.
