General. A multimeter is used to troubleshoot the electrical system of the roller. The multimeter ohms scale is used to
Continuity Tests. Continuity tests are performed
to check for
breaks in a circuit
(such as a fuse, switch, light bulb con-
nector or electrical wiring).
If readout will not zero properly, replace batteries and repeat zeroing procedure. If readout will not zero after
batteries have been replaced, notify your supervisor.
Set multimeter to ON.
Select LOWEST VOLTAGE/OHMS scale.
Touch black and red probes together and check for a zero indication on digital readout.
Before performing a continuity test, always place battery disconnect switch in OFF (TM 5-3895-379-10)
position and disconnect circuit to be tested. Failure to follow this caution may damage multimeter.
Testing for Continuity.
Connect black and red probes to both terminals of circuit being tested.
Observe readout and interpret results as follows:
(a) If readout indicates any numeric value, circuit has continuity.
(b) If readout does not indicate any numeric value, or value is over the limits of the meter, circuit is open.
