ACA Current clamp-on function
Inputs are made through the jaws clamps for non-invasive ACA current measurements.
CAUTION
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.
Strong Electro-magnetic field environments such as high-current transformers, motors
and conductors may affect measurement accuracy.
