Page 8: Why Test Is Necessary
Wavecom Instruments Insulation-Continuity Tester User Manual 6. Why Test is Necessary? INSULATION Every electrical apparatus and installation need to be safe for the user and for the equipment itself. Electrical conductors of electricity need to be insulated from each other, so that they do not create electrical hazard or unnecessary consumption. -

Wavecom Instruments Insulation-Continuity Tester User Manual CONTINUITY TESTS - Ω RANGES 1. Select the desired ohm range, 3Ω or 500Ω. 2. Short the test leads, press test button and adjust the ohms zero ADJ to zero the pointer on the 0Ω (green scale). -
Page 12: Functions
Wavecom Instruments Insulation-Continuity Tester User Manual 10. Functions 10.1 Battery Check Turn the function selector to Batt. Check. This function has a load which draw about 205mA when test is performed, and therefore it is doing a worst case battery test. - Page 13 Wavecom Instruments Insulation-Continuity Tester User Manual 10.2 DC Warning The DC warning buzzer will beep continuously when DC voltage is higher than 30Vdc on the test probes and the test button is not pressed. The neon light "circuit live" will illuminate when the voltage on the test probes is higher than 90Vdc and the test button is not pressed.
