Voltmeter/Ohmmeter Mode

NOTE: The DRB-II is grounded through diagnostic connector and only one test lead is required. When diagnosing transmission, an external volt-ohmmeter may sometimes be required.
  1. To access voltmeter/ohmmeter mode, connect Red volt-ohmmeter test lead to Red port at top right corner of DRB-II. There are 2 different ports on top of DRB-II; ensure test lead is connected to proper port.
  2. To access voltmeter mode, press VOLT/OHM key one time. Touch test lead to connector or wire, and note voltage reading on DRB-II. When voltage reading is complete, press VOLT/OHM key 3 times to exit voltmeter mode.
  3. To access ohmmeter mode, press VOLT/OHM key 2 times. Touch test lead to connector or wire, and note resistance reading on DRB-II. When resistance reading is complete, press VOLT/OHM key 2 times to exit ohmmeter mode.
