8.3 Determine the Problem
Determine whether the problem is in the PCB or the Load Cell
Disconnect the power supply from the scale, and disconnect the load cell
connection from the PCB
Reapply power and test the PCB
If problem goes away, its source is probably in the Load cell. Check the wiring,
connecter, load cell and mechanical components of the load cell.
If problem persists, its source is probably in the PCB. Check the PCB
voltages, connecters, cables and function programs
