Using Source Mode
In SOURCE mode, the calibrator generates calibrated
signals for testing and calibrating process instruments;
supplies voltages, currents, frequencies, and resistances;
simulates the electrical output of RTD and thermocouple
temperature sensors; and measures gas pressure from
an external source, creating a calibrated pressure source.
Sourcing 4 to 20 mA
To select the current sourcing mode, proceed as follows:
1.
Connect the test leads in the mA terminals (left
column).
2.
If necessary, press

Simulating a 4- to 20-mA Transmitter
Simulate is a special mode of operation in which the
calibrator is connected into a loop in place of a
transmitter and supplies a known, settable test current.
Proceed as follows:
1.
Connect the 24 V loop power source as shown in
Figure 14.
