I have and OF4 configured for 4-20mA. How can I test the current output from a 1762-OF4 on the lab bench. i.e. the OF4 does not have a load attached. Just putting a ammeter between COM and “I out 0” does not work. I tried using a 100 ohm resistor as a load, but that didn’t work either? The manual says “Resistive load on current output can be 0 to 500 ohms. What can I use to simulate a load? I am pretty sure that the card is OK. I tried it as voltage output (configured accordingly) and it worked perfectly.
