OPERATING INSTRUCTIONS
RESISTANCE MEASUREMENTS
1. Insert RED test lead into VΩ jack
5
, and BLACK test lead
into COM jack
4
, and rotate function selector switch
2
to the
highest Ω setting (2MΩ).
2. Remove power from circuit.
3. Measure resistance by connecting test leads to circuit and
rotating the function selector switch
2
to successively
lower Ω settings to obtain higher resolution measurements.
NOTE:
When in a Resistance setting and the test leads are open
(not connected across a resistor), or when a failed resistor is under
test, the display will indicate O.L. This is normal.
DO NOT attempt to measure resistance on a live circuit.
CONTINUITY
1. Insert RED test lead into VΩ jack
5
and BLACK test lead into COM
jack
4
, and rotate function selector switch
2
to the
setting.
2. Remove power from circuit.
3. Test for continuity by connecting conductor or circuit with test
leads. If resistance is measured less than 100Ω, an audible
signal will sound and display will show a resistance value
indicating continuity. If circuit is open, display will show "
OL
".
DO NOT attempt to measure continuity on a live circuit.
