Using the 700-IV Current Shunt

To source and measure current simultaneously, you
need to use a current shunt and use the volts
measure function. The Fluke 700-IV current shunt is
designed specifically for use with the 700 Series
Documenting Process Calibrators. To measure
current with the current shunt, proceed as follows:
1. Connect the current shunt to the MEAS V jacks
(rightmost).
2. Connect the current signal to be measured to the
current shunt.
3. Select the dc voltage measure function.
4. Press the softkey.

5. Select

6. The calibrator is automatically configured using
custom units appropriate for the current shunt.

Damping Your Measurements

The calibrator normally applies a software filter to
dampen measurements in all functions except
continuity. The specifications assume that damping is
turned on. The damping method is a running average
of the last several measurements. Fluke
recommends that you leave damping on. Turning
damping off may be useful when measurement
response is more important than accuracy or noise
reduction. If you want to turn off damping, press the
softkey twice, then press the
More Choices
softkey so that appears. Press
Off
turn damping back on. The default state is
Dampen
again to
