i1000s
AC CURRENT PROBE FOR OSCILLOSCOPES
Quick Reference Card
Read Safety Information found in the i1000s
Users Manual before use.
OPERATION
To make a measurement, follow these steps and refer to the
illustration on the back. (Steps are identified in the illustration.)
Connect the i1000s Current Probe to the desired input
1
channel on the oscilloscope.
2
On the Current Probe, select the least sensitive range (1
mV/A).
3
On your oscilloscope, select an appropriate range.
Clamp the probe around the conductor to be measured,
4
and observe the current waveform on your oscilloscope
display. For standard oscilloscopes, use a 1:1 probe
setting. Not needed for Fluke ScopeMeter 123.
MEASUREMENT CONSIDERATIONS
Observe the following guidelines for positioning the Current
Probe jaws:
Carefully move the probe to center the conductor inside
•
the jaws.
Make sure the probe is perpendicular to the conductor.
•
If possible, avoid measurements close to other currentcarrying conductors.
•
On the Current Probe, the 1 mV/A range offers the best
accuracy and least phase shift. When using the 1 mV/A probe
range, use the “volts per division” adjustment on your
oscilloscope for best display results.
