6) Power on the module 

7) Keep pushed the calibration button (or in alternative, only for Z-SG model, use digital input) 
until LED ERR is “ON” 

8) Release the calibration button 

9) Control that the LED ERR is flashing 

10) Put the tare on the load cell 

11) Keep pushed the calibration button (or in alternative use digital input signal for Z-SG model) 
until LED ERR switches from flashing to “OFF” 

The module has acquired the tare value. 

12) Keep pushed the calibration button (or in alternative use digital input signal) until LED ERR 
is “ON” 

13) Release the calibration button 

14) Control that the LED ERR is flashing 

15) Put the known weight on the tare  

16) Keep pushed the calibration button (or in alternative use digital input signal) until LED ERR 
switches from flashing to “OFF” 

The module has acquired the known weight value. 

17) Power off the module 

18)  Switch  the  Dip-Switches  SW2-

4  to  “OFF”  and  SW2-5  to  “ON”.  In  this  way,  the  module  is 

calibrated. 

19) Power ON the module 

 

If the module is power off during this procedure, calibration setting is lost. Restart the 

calibration procedure from the first point.
