The analogue output shows constant 0V or 0mA or 4mA

Troubleshooting at a constant output signal

Please check:

  • was set zero adjustment done (via pushbutton or digital input)
  • zero adjustment was carried out at the right time (when the silo was empty when the power was minimal), otherwise the measured value decreases with decreasing level below 4mA or below 0V
  • Supply voltage to the DMS test (2.5V or 5V)
  • Output voltage of the load cell test (less than + - 1 mV)
