Fluke 707 - mA Sourcing Modes; Using mA Sourcing

English Instruction SheetPanel 4
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 COM
terminals. Otherwise the display indicates an overload (OL) when
you set an output value.
