Documenting Process Calibrator

Simulating a 4 to 20 mA Transmitter
You can configure the calibrator as a load on a
current loop through the SOURCE mA function.
When you press the M key in SOURCE mode, the
display prompts you to select Source mA or
Simulate Transmitter. The difference in operation is
that when you Source mA the calibrator is sourcing
current, and when you Simulate Transmitter the
calibrator is sourcing a variable resistance to
regulate current to the specified value. Connect an
external loop supply to the positive (top) mA jack as
shown in Figure 15.
