Using the Meter
Using the LOCK Function to Measure Insulation Resistance
The LOCK function holds the test voltage on the probes. Use LOCK to make long duration measurements without having to push and hold the TEST button.
To use the LOCK function:
1.Press the TEST button, then press the LOCK button, and then release both simultaneously.W
Warning
In this mode a potentially dangerous voltage is continuously applied to the probes.
In this mode, if the probes are disconnected from the circuit, the Meter cannot discharge any potentially dangerous capacitive voltages left on the circuit.
Caution
In this mode the Meter cannot indicate if the circuit is live.
Ensure that the circuit is
2.Press LOCK or TEST to disengage the lock function.
