Using the mA Sourcing (Output) Modes
The Calibrator outputs current for calibrating and testing
0 to 20 mA and 4 to 20 mA current loops and instruments.
In SOURCE mode, the Calibrator supplies the current.
In SIMULATE mode, the Calibrator simulates a 2-wire
transmitter in an externally powered current loop.
Changing the mA Output Span
The Calibrator has two mA output spans:
• 4 mA to 20 mA (0 % to 100 %) [default]
• 0 mA to 20 mA (0 % to 100 %) [optional]
To change the output span, turn the Calibrator off. Press
A + D simultaneously. The selected setting is saved
until it is changed again.
Sourcing mA
Use SOURCE mode to supply current to a passive circuit.
A path must exist for current to flow between the + and
the COM terminals. Otherwise, the display flashes when
you set an output value.
