Measuring continuity

To avoid measurement errors and the risk of an electric shock, before making continuity
measurements on a circuit, check that there is no voltage in the circuit.
1. Turn the rotary switch to
make sure power is disconnected
from the circuit to be measured.
2. Connect the red test lead to the +
terminal and the black test lead
to the COM terminal
3. Detect the continuity by touching
the probes to the desired point of
the circuit, if the resistance is
under 50Ω, the beeper will
sound, designating a short circuit.
If the resistance is above 600Ω,
the meter displays OL,
designating an open circuit.
3.7.

Measuring resistance

To avoid measurement errors and the risk of an electric shock, before
making resistance measurements on a circuit, check that there is no voltage
in the circuit.
With the continuity mode selected, press the yellow button once to activate the
resistance measurement. Touch with the test probes the desired point of the circuit and
read the measured resistance on the display. If resistance is above 60MOhm the meter
will display OL.

Testing Diodes

To avoid measurement errors and the risk of an electric shock, check, before
testing diodes, that there is no voltage in the circuit.
