How to Use the DRBII Volt/Ohmmeter

NOTE: The Volt/Ohmmeter function will not operate in the Read Fault Data or the Erase Fault Data section.





MAKING VOLTAGE MEASUREMENTS
1. Connect the red Volt/Ohmmeter test lead to the DRBII.
2. Press the Volt/Ohm key on the keypad once.

NOTE: The DRBII will remember what Test Mode you are in while in the Volt/Ohmmeter function and will return to that mode when you are done using the Volt/Ohm function.

3. Touch the test probe to the connector or wire to be measured and read the results on the DRBII display.
4. After all measurements have been made, press the Volt/Ohm key twice to return to the Test Mode you were in before you entered the Volt/Ohmmeter function.

MAKING OHMMETER MEASUREMENTS
1. Connect the red Volt/Ohmmeter test lead to the DRBII.
2. Press the Volt/Ohm key on the keypad twice.

NOTE: Because of the way the DRBII Ohmmeter is configured (one lead), you will only be able to test wires or components to ground.

3. Touch the red test probe to the wire or component you wish to test and read continuity to ground on the DRBII display.
4. After all measurements have been made, press the Volt/Ohm key once to return to the Test Mode you were in before you entered the Volt/Ohmmeter function.





USING A DIGITAL VOLT/OHMMETER FOR RESISTANCE MEASUREMENTS
When using a digital volt/ohmmeter to check resistance, make sure you determine any built in resistance of the meter by touching both leads together. For example, after touching leads together, meter indicates 0.6 ohms. This is your 0 point. When checking the circuit resistance 0 ohms would be 0.6 ohms and 1/2 ohm resistance would be 1.1 ohms.
