sensitivity. Activating the Hz function WHILE measuring the specific function signal (auto
ranging) can automatically select the best sensitivity range to avoid electrical noise which may
cause unstable Hz reading. However, if the Hz reading shows zero due to insufficient sensitivity,
activate the Hz function BEFORE measuring the specific function signal (the meter is then in the
lowest range) can select the highest sensitivity range.
CAUTION
Using Resistance, Continuity, Diode or Capacitance function in a live circuit will produce false
results and may damage the instrument. In many cases the suspected component must be
disconnected from the circuit to obtain an accurate measurement reading

Continuity function which is convenient for checking wiring
connections and operation of switches. A continuous beep tone indicates a complete wire.

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)
