Error Messages & Solution 

 

7.1.

 

Beep: Re-zero 

The range of “Re-zero” is within 

±

 2% of full capacity. However, when the scale is out of this 

range it automatically beeps to notify to user that “Re-zero” function does not work in this 
range.  

 

7.2.

 

Err: Initial Zero 

You may set 2% or 10% of full capacity as Initial Zero.   
When you place an item more than the initial zero setting value (2% or 10% of full capacity) 

and turn on the scale it display “Err” message and does not work.   

However, you can make the scale work if you make the item’s weight be within the initial 

zero setting range (2% or 10% of full capacity) by decreasing the value of weight.   

 

7.3.

 

Init: Failure of Analog Module 

“Init” message shows up when there is some problem on analog module.   
Please turn off the scale and turn on. If you still have “Init” message on display please 

contact CAS A/S service.

   

 

7.4.

 

UNSTA: A/D Value Unstable 

 

The scale displays “UNSTA” when it is in unstable status or in low-power supply.   
If the scale is not properly balanced, 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. And if the scale is in low power supply please replace the battery or plug in 
adapter. 

However, if you still have 

UNSTA

 problem please contact CAS A/S service.
