DRB Volt/Ohmmeter Mode

To access volt/ohmmeter mode of DRB, connect Red volt/ohmmeter test lead to Red port, located on right-top side of DRB.

To access voltmeter, press VOLT/OHM key once. DRB is now in voltmeter mode. Touch test probe to connector or wire to be measured. Read voltage on DRB display. When voltage testing is complete, press VOLT/OHM key 3 times to exit voltmeter mode.

To access ohmmeter, press VOLT/OHM key twice. DRB is now in ohmmeter mode. Touch test probe to connector or wire to be measured. Read resistance to circuit ground on DRB display. When resistance testing is complete, press VOLT/OHM key twice to exit ohmmeter mode.
