Page 6: Measuring Methods
4. Measuring Methods OPERATION CAUTION Observe all safety precautions when the FUNCTION switch is set to either the 200MΩ(250,500V) or the 2000MΩ(1000V) position. Connect the meter test leads to the circuit under test before operating the TEST switch. Do not touch the clip ends of the test leads when the TEST switch is pressed. - Page 7 ● TEST switch: The TEST switch is normally OFF, spring loaded, momentary action switch which "turns on" the meter. The momentary action is a safety feature. The test voltage generated by the meter is automatically discharged when the TEST switch is released. Always check the following before testing: The "Battery Low"...
- Page 8 1. Select the required test voltage (250V, 500V or 1000V) by rotating the FUNCTION switch. 2. Connect the test leads to the instrument and to the circuit to be tested.(See connect diagram) If the "LIVE CIRCUIT" is light, do not press the TEST button and disconnect the instrument from the circuit.
- Page 9 When testing is complete ensure that the TEST switch is released before the test leads are disconnected. This is because the system may be charged up and it must be allowed to discharge through the instrument's internal discharge resistor. ● Continuity discharge (Resistance test) Warning Ensure circuit is not live before commencing testing.
