VII. OPERATION :
WARNING :
Before and after hazardous voltage measurements,
test the voltage function on a known source such as line voltage to
determine proper meter functioning.
ACV :
Inputs, are made through the test lead terminals

at
ACV
Function.
Note : ACV
function is equipped with low-pass filter, & is capable of
dealing with
VFD
(Variable Frequency Drive) signals. It also improves
ACV reading stability in noisy electrical environments.

Clamp-on Current Measurements :
Application & Removal of the Jaws
Press the jaw trigger & clamp the jaws around conductor(s) of only
one single pole of a circuit for load current measurements. Make
sure the jaws are completely closed, or else it will introduce measure-
ment errors. Enclosing conductors of more than one pole of a circuit
may result in differential current (like identifying leakage current)
measurements. Align the conductors to the Jaws center indicators
(Regular or AmpTipTM indicators where applicable) as much as
possible to get the best measuring accuracy. For removal, press the
jaw trigger and remove the jaws from the conductors.
Adjacent current-carrying devices such as transformers, motors and
conductor wires may affect measurement accuracy. Keep the jaws
away from them as much as possible to minimize influence.
WARNING :
This Clamp-on meter series is designed to directly apply around or
remove from uninsulated hazardous live conductors. But still,
individual protective equipment must be used if hazardous live parts
in the installation where measurement is to be carried out could be
accessible. Do not use the meter to measure currents above the
rated frequency (400Hz). Circulating currents may cause the
magnetic circuits of the Jaws reach a hazardous temperature.
