Fluke model 789 sourcing current

[@BTCInstrumentation]

In "source" mode the calibrator is actually the power source for the circuit, both motivating and regulating current. In "simulate" mode the calibrator only regulates current (passively), and relies on some other power source in the circuit to motivate current. In other words, in "simulate" mode the calibrator is an electrical load; in "source" mode it is an electrical source.

Thanks for this info.
Say I have a transmitter that has a separate 24VDC power on 2 wires, and 2 wires for 4-20mA signal. In this case I should use "SIMULATE" on the calibrator, correct?

What's the difference between "sourcing" and "simulating" a 4-20mA?
