Measuring Resistance

XW Warning
To avoid electrical shock or damage to the
Meter when measuring resistance or
continuity in a circuit, make sure the power to
the circuit is turned off and all capacitors are
discharged.
1. Turn the rotary switch to
disconnected from the circuit to be measured.
2. Connect the red test lead to the
black test lead to the COM terminal.
3. Measure the resistance by touching the probes to the
desired test points of the circuit.
4. Read the measured resistance on the display.

Testing for Continuity

With the resistance mode selected, press the YELLOW
button twice to activate the continuity beeper. If the
resistance is under 50 Ω, the beeper will sound
continuously, designating a short circuit. If the meter reads
o, the circuit is open.
