Using the Current Output Modes
The calibrator provides current output in mA or percent display.
Percent is -25.00 to 125.00%, where 0% is 4 mA, and 100% is 20
mA.
In source mode, the calibrator supplies the current. In simulate
mode, the calibrator simulates a two-wire transmitter in an
externally-powered current loop.
Sourcing mA
Use source mode whenever you need to supply current into a
passive circuit such as a current loop with no loop supply. Insert
the test leads into the OUTPUT + and − mA jacks as shown
below.
Note
A path must exist for current to flow between the
OUTPUT
+
and
−mA
jacks, otherwise the display will
indicate an overload (OL) when you set an output value.
