744 Users Manual 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 Scale softkey. 5. Select Current Shunt from the list. 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 More Choices softkey twice, then press the Dampen softkey so that Off appears. Press Dampen again to turn damping back on. The default state is On. 44

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
Scale
softkey.
5.
Select
Current Shunt
from the list.
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
More Choices
softkey twice, then press the
Dampen
softkey so that
Off
appears. Press
Dampen
again to
turn damping back on. The default state is
On
