AC Current Probe

Operation

Use the following procedure to make a measurement:

1. Connect the i1000s Current Probe to the desired input channel on the

oscilloscope.

2. On the Current Probe, select the least sensitive range (1 mV/A). See

Figure 1 for selector switch location.

3. On your oscilloscope, select an appropriate range. Use a 1:1 probe setting.

Note

If using the Fluke ScopeMeter 123, use this procedure for step 3:

1. Press

(shown in Figure 3).

2. When the MEASUREMENTS screen appears, select AMP…

and ENTER.

3. When ENTER is pressed, the AMPERE PROBE screen

appears.

4. Select the appropriate range (i.e. 1 mV/A).

4. Clamp the probe around the conductor to be measured, and observe the

current waveform on your oscilloscope display.

Note

If using the Fluke 123 ScopeMeter, disregard the next step.

5. Calculate the Amps-per-division on your oscilloscope by dividing the

vertical scale (mV or V per division) by the i1000s switch position

(1, 10, or 100 mV/A). For example:

20 mV per division = 20 A per division

1 mV/A

Setups using the Current Probe and a ScopeMeter are shown in Figure 3.
