What to do if I'm not getting the expected 4-20mA output from my McCrometer ProComm HL Media Converter?
- N
  Nathaniel SandersAug 3, 2025
  If you are not getting the expected 4-20mA output, make sure the wiring is firmly connected to the 4-20mA output terminals. Also, verify that the resistor has been removed from the terminal block and that the FS1 setting in the main menu is set to the correct value, matching the PLC/SCADA value. Finally, measure the output on the 4-20mA terminals and compare it to the calculated current value.

What to do if my McCrometer ProComm HL Media Converter shows a 'Curr. Loop Open Alarm'?
- A
  Amy FullerAug 7, 2025
  If your McCrometer Media Converter displays a 'Curr. Loop Open Alarm', ensure the wiring is firmly connected on the 4-20mA output terminals. If the 4-20mA output is not being used, ensure the 4-20mA terminals have a load resistor installed. You can also remove the wires from the 4-20mA terminals and measure the current output directly.

Why are my flow readings unstable on the McCrometer ProComm HL?
- C
  Christopher OconnorAug 12, 2025
  Unstable flow readings can occur if the installation straight run requirements are not met. Check the grounding connections and the power circuit for other devices. Consider installing a dedicated ground circuit.

  If your McCrometer Media Converter shows an 'Empty Pipe Alarm', try increasing the threshold to 250 kΩ. Confirm the pipe is full, and if it is always full, turn off EP Detect. Check that the sensor is properly grounded and inspect the cable between the sensor and converter for damage. You can also conduct a bucket test to confirm the EP Threshold value is set correctly.
