Expert’s answer: Micro Motion 1700 output

Hey, we got this! The Micro Motion 1700 output is an active signal, so you don’t need a power supply. Pay attention to your loop installation – maximum loop resistance cannot exceed 820 ohms.

If the values are within the correct intervals, then do a quick check using a loop tester. Simulate a 4-20 mA output and inspect your cables to cross off structural problems. A faulty cable could be the culprit.

Now grab the handheld and dive into the HART interface. (If you need help connecting the handheld, see the pictures below.)

Before connecting the signal cables to the Micro Motion 1700, use a multimeter to confirm you have voltage from your device. Connect the signal cables and simulate the output signal using the built-in function:

Simulate > Simulate Outputs > mA output loop test (select the mA)

Now you can do the configuration. If you’ve checked all of the above and still have trouble, you may need to contact Emerson’s tech support, as the problem could be with the device itself.
