Measuring Leakage Current
Measuring load current
To measure load current, clamp just one wire of the conductor.
The measurement will not be possible if you clamp both wires of a
single-phase cable or all 3 wires of a 3-phase cable.

• The instrument may not be able to measure certain special
waveforms, for example on the secondary side of an inverter.
• Depending on the magnitude and frequency of the input
current, resonance may cause the jaws to emit noises, but
this will not affect the measurement.
• If you don't know the magnitude of input current, disable the
lter function and begin measurement with auto ranging or
with the 200 A range set.
