744 Users Manual 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. 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 17. Note Also see "Transmitter Mode," in which the calibrator can be set up to temporarily take the place of a two-wire process transmitter. 48

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
. When you
Source mA

regulate current to the specified value. Connect an
external loop supply to the positive (top) mA jack as
shown in Figure 17.
Note
Also see “Transmitter Mode,” in which the
calibrator can be set up to temporarily take
