1. Introduction1.1. 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 EB series.

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.

Description 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 hasshifted 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 4" The "Err 4" is leakage of payment. Scale needs morepayment.

"Err 5" The "Err 5" means there is already tare. Remove the tare.

"Err 6" The "Err 6" means total price summation is

over.

Please change unit price

or remove some weight.

"Err 7" The "Err 7" means total price is over. Please change unit price
