ACA Current clamp-on function
Inputs are made through the clamp on jaws for non-invasive ACA current measurements.
Press the OFF push button momentarily to power on and off the separate ACA function
(upper) display. The MAX HOLD push button can also be used to power on this function.
This twin ACA function display can be used simultaneously with voltage measurements or
any of the other slide-switch functions (lower display) or it can be used alone.
CAUTION
Clamp the jaws around only one single conductor of a circuit for load current
measurement. Enclosing more than one conductor of a circuit will result in differential
current (like identifying leakage current) measurement.
