If the current loop is stuck at 4 mA or 20 mA on your Endress+Hauser Measuring Instruments, check the display for an error message. Additionally, on the current loop board, check the voltage between the end of resistor R1 closest to the jumper and ground.
Why are there strange characters on Endress+Hauser Measuring Instruments display?
If strange characters appear on the front panel display of your Endress+Hauser Measuring Instruments, check the connections on the display communication cable.
Why does Endress+Hauser Measuring Instruments display 0.0 or low reading?
If the reading displays 0.0 or seems relatively low on your Endress+Hauser Measuring Instruments, check that Peak Tracking is enabled.
