Continuity Testing

The DVOM uses its own internal power supply to test the continuity of the circuit. The DVOM must never be connected in a live circuit. Any circuits wired in parallel with the circuit being tested must also be disconnected.

Continuity testing verifies that circuit connections are intact. The continuity mode is extremely fast and is used to detect either shorts or opens that last as little as 1 ms.

When a change is detected the beeper tone is stretched to last at least 1/4 second so both shorts and opens can be audibly detected.

This is a valuable troubleshooting aid when diagnosing intermittent faults associated with wiring, connections, switches and other components of the circuit.

• Select correct function and range of DVOM.
• Disconnect power to the circuit.
• Disconnect any circuits wired in parallel.
• Connect DVOM leads to the circuit to be tested.
