Fluke 707 [4/16] Changing the ma output span

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.
