The 4-20 mA output is wrong

Reason

Solution

Analog output settings incorrect.

  1. Check analog output settings.
  2. Run Simulate current output and verify the correct output.

Sensor and data acquisition system have different grounds.

Verify that sensor and data acquisition system have the same ground.

The analog output is read by a data acquisition system and the scaling in wrong.

Verify scale and offset on your data acquisition system.

Two or more analog outputs of the PQ are read by a data acquisition system and the wiring is wrong, e.g. IOUT1 is read as IOUT2.

Verify the wiring on your data acquisition system and swap the wires if required.

The 4-20 mA output is delayed by approx. 150 ms. If the output is read before, a wrong value is acquired.

Sample the 4-20 mA output with a delay of more than 150 ms.
