5. Current measurement
Connect the output lead to a multimeter. Select the AC or DC mV
range on the multimeter as appropriate to the current measurement.
If necessary adjust the probe output voltage to zero as described in
Step 4. Clamp the jaws of the probe round the conductor ensuring a
good contact between the closing faces of the jaws.
Observe and take measurement as required. Positive output
indicates that the current flow is in the direction shown by the arrow
on the probe.
True RMS readings can be obtained by using an appropriate true
RMS reading multimeter. Core eddy current heating is produced
when I RMS x f > 400.000. This will limit the maximum measurable
current at high frequencies.
