How to Use the DRBII Volt/Ohmmeter

To access the volt/ohmmeter function of the DRBII, proceed as follows.





A. Connect the red volt/ohmmeter test lead to the red port at the right top of the DRBII.

NOTE: There are two ports at the top of the DRBII. Be sure to connect the lead to the correct port.

Voltmeter Mode
A. Press VOLT/OHM once. The top line of the display will change to read as follows:

*-VOLTS= .X--*

B. Touch the test probe to the connector or wire to be measured.
C. Read the voltage on the DRBII display.
D. When voltage testing is done, press VOLT/OHM three times to exit voltmeter mode.

Ohmmeter Mode
A. Press VOLT/OHM twice. The top line of the display will change to read as follows:

*- OHMS = XX -*

B. Touch the test probe to the connector or wire to be measured.
C. Read the resistance to ground on the DRBII display.
D. When resistance testing is done1 press VOLT/OHM twice to exit ohmmeter mode.

NOTE: Some test steps require the use of an ohmmeter other than the DRBII ohmmeter. Before using an "external" ohmmeter, be sure it is properly adjusted to take accurate readings of resistance. Refer to the manufacturer's operating instructions if necessary.

Continuity Meter Mode
A. Press VOLT/OHM three times. The top of the display will change to read as follows:

*-NO CONTINUITY-*

B. Touch the test probe to the connector or wire to be measured.
C. Read the continuity on the DRBII display.
D. When continuity testing is done, press VOLT/OHM once to exit continuity meter mode.
