Calibration of the new load cell will be required and a check for Repeatability,
Off centre loading and Linearity should be made.
Main PCB faults are very rare, if you have a problem where power to the PCB
is correct and the load cell has been checked and confirmed as fully functional
then replacement of the Main PCB is the most effective method of repair.
If this is the case, the PCB number and model of machine should be made
clear so that the PCB can be programmed and checked first, once checked
the PCB can then sent to be fitted directly to the Indicator.
Calibration can then be performed and the unit should function correctly
