Measuring Methods

6.1. Operation caution
Observe all safety precautions when the FUNCTION switch is set to either the 200 MΩ (250, 500 V) 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. Some electrical equipment, especially cables, may retain an electrical charge when disconnected from the line. It is good practice to discharge such equipment with grounding straps, or other suitable devices,
before touching or making connections. The meter automatically discharge the test circuits when the spring loaded TEST switch is released.
6.2. Important
Remove all power to the circuit under test when making resistance measurements. If any voltage is present in the test circuit the red on the meter scale plate will light. Immediately disconnect test leads and turn off power to test circuit.
6.2.1. Function switch
The FUNCTION switch is used to select the range, or function desired.
6.2.2. Test switch
The TEST switch is normally OFF spring loaded momentary action switch which “turn on “ the meter is momentary action is a safety feature. The test voltage generated by the meter is automatically discharged when the TEST switch is released.
6.2.3. Before testing always check the following
The “battery low” indicator is not shoving. There is no visual damage to the test or test leads. Test Lead Continuity. Select the continuity function and 20Ω  range. Short the test leads together. An overrange (“1”) indication will mean that the leads are faulty or instrument fuse is blown. (see fuse replacement).
6.2.4. Insulation Resistance Testing
WARNING!
Insulation test should be conducted on circuits that are deenergised.
Ensure circuits are not live before commencing testing.

•  Select the required test voltage (250 V, 500 V or 1000 V) by rotating the function switch.
• Attach the test leads to the instrument and to the circuit to be tested (see connect diagram). If the “LIVE CIRCUIT” is lit, do not press the test button and disconnect the instrument form the circuit. The circuit is live and should be de-energised before further testing.
•  Press the test button. The value of insulation resistance in megohms will be displayed.

CAUTION: Never turn the function dial whilst the button is depressed. This may damage the instrument. Never touch the circuit under test during insulation testing.
When testing is complete ensure that the test button 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 tester’s internal discharge resistor.
6.2.5. Continuity testing (Resistance test)
WARNING!
Ensure circuit are not live before commencing testing.

• Select the 20 Ωrange by rotating the range selector and connect the test leads to the instrument. Short the tips of the leads. Press and hold down the test button by twisting it a quarter turn clockwise. The display will show the resistance of the test leads. Adjust the Ω ZERO control to set the reading of zero.
• Connect the test leads to the circuit under test. Ensure the circuit is not live by checking that the live circuit indicator does not lit. Read the value of resistance from the LCD.
  6.2.6. AC voltage test
  Set FUNCTION switch to ACV. Connect test leads to circuit being measured. Press TEST button and read the value of voltage from the LCD.
