CAUTION (Application and removal of the Clamp-on meter)
For non-invasive current measurements, press the jaw trigger and clamp the jaws
around conductor(s) of only one single pole of a circuit for load current measurement.
Make sure the jaws are completely closed, or else it will introduce measurement errors.
Enclosing conductor(s) of more than one pole of a circuit may 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. For removal,
press the jaw trigger and remove the jaws from the conductor(s).
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.
