    Operation refer to safety wa rnings before using the instrument testing is automatically inhibited if: • an external voltage >55v is present when switched to any insulation range position • an external voltage >10v is present on all other ranges (excluding off/v ). The external voltage is indicated ...

    Operation alternatively the key can be re-pressed. Insulation tests (m Ω ) (see fig. 1) the insulation tests apply a known voltage to the circuit under test and measure the resulting leakage current. The circuit under test must be completely de-energised and isolated before test connections are made...

    Operation the reading will hold for a few seconds and then reset. This range is not suitable for diode testing since the automatic contact detector will not be activated when connected to a diode. 1. Set the selector switch to Ω . 2. Connect the test leads. 3. The test will activate automatically. 4...
