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.

Note
When using Diode test function, normal forward voltage drop (forward biased) for a
good silicon diode is between 0.400V to 0.900V. A reading higher than that indicates a
leaky diode (defective). A zero reading indicates a shorted diode (defective). An OL
indicates an open diode (defective). Reverse the test leads connections (reverse
biased) across the diode. The digital display shows OL if the diode is good. Any other
readings indicate the diode is resistive or shorted (defective).
CAUTION
1. Using Resistance, Continuity, Diode or Capacitance function in a live circuit will
produce false results and may damage the meter. In many cases the suspected
component(s) must be disconnected from the circuit to obtain an accurate
measurement reading.
2. When using Capacitance function, discharge capacitor(s) before making any
measurements. Large value capacitors should be discharged through an appropriate
resistance load
