Documenting Process Calibrator

Using Source Mode

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.
