When voltage or current function is selected, press and hold THD%-R button for one

second or more toggles to Total Harmonic Distortion - RMS measurement function. The LCD

annunciator "%" turns on.

Note:

Specified accuracy at ACA fundamental > 5A; ACV fundamental > 50V.

The meter displays "---.- %" when ACA fundamental < 1A; ACV fundamental <8.5V

ACA Current clamp-on function

Set the slide-switch function-selector to the

position. Inputs are made through the clamp

jaws for non-invasive ACA current measurements.

CAUTION

●For non-invasive ACA current measurements, press the jaw trigger and clamp the jaws

around only one single conductor of a circuit for load current measurement. Make sure the

jaws are completely closed, or else it will introduce measurement errors. Enclosing more

than one conductor of a circuit will result in differential current (like identifying leakage

current) measurement.

●Adjacent current-carrying devices such as transformers, motors and conductor wires will

affect measurement accuracy. Keep the jaws away from them as much as possible to

minimize influence.
