ACA & DCA Current clamp-on function

Inputs are made through the clamp jaws for non-invasive ACA & DCA current

measurements.

CAUTION (Application and removal of the Clamp-on meter)

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. Locate the

conductor(s) at the Jaws center as much as possible to get the best measuring

accuracy. The jaw arrow-mark indicates current flow direction on DCA positive

readings. For removal, press the jaw trigger and remove the jaws from the

conductor(s).

Note: In DCA measurements, hysteresis of the jaws (after measuring high DC currents)

may introduce non-zero residual readings. Relative Zero

mode should be used to

offset the residual readings, if any, so as to get more accurate measurements.

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.
