DRB-II Volt/Ohmmeter Mode
- To access volt/ohmmeter mode of DRB-II, connect Red volt/ohmmeter test lead to Red port, located on right-top side of DRB-II.NOTE: Because DRB-II is grounded through data link connector, only one volt/ohmmeter test lead is required when using volt/ohmmeter option. DRB-II volt/ohmmeter should only be used when diagnostic procedures require it.
- To place DRB-II in voltmeter mode, press VOLT/OHM key once. Touch test probe to connector or wire to be measured. Read voltage on DRB-II display. When voltage testing is complete, press VOLT/OHM key 3 times to exit voltmeter mode.
- To place DRB-II in ohmmeter mode, press VOLT/OHM key twice. Touch test probe to connector or wire to be measured. Read resistance to circuit ground on DRB-II display. When resistance testing is complete, press VOLT/OHM key twice to exit ohmmeter mode.
