The 3 loop test can be done with the Yokogawa ROTAMASS display. In fact, you can do it with your handheld too, but I’ll go through the display steps with you.

Go to option labeled Diagnostic/Service and find the input/output test. There you can test all device outputs, so choose the one you want to test and simulate the value. Then you can check the values using a multimeter!

If you want more information about the loop test, here you can see the setting ranges:
