1. 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 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.

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.

6. Error Messages & Solution

Error

Message

on Display

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 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.


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 more

payment.

"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

or remove some weight.

"Err 8" The "Err 8" means Euro rating price is over. Please change unit price

or change euro rate.

“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 13” The "Err 13" means the soft key code is broken.

Please try to find out which

key lost soft key code and

then input this code again.

“Err 14” The "Err 14" means calibration range is not

correct.


dealer.

“Err 15” The "Err 15" means 1/2 or 1/4 unit price is over. Please change unit price
