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.

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.

IMPORTANT

Remove all power to the circuit under test when

making resistance measurements. If any voltage is

present in the test circuit the LED on the meter scale

will light. Immediately disconnect test leads and turn

off power to test circuit.

●FUNCTION switch:

The FUNCTION switch is used to select the range,

or function desired.

-5-

●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" indicator is not showing.

There is no visual damage to the instrument or test

leads.

●Test lead continuity

Select the CONTINUITY function and 20Ω range.

Short the test leads together.

An over-range ("1") indication will mean that the

leads are faulty or instrument fuse is blown. (See

"Fuse Replacement" section)

●Insulation resistance test:

Warning

Insulation tests should be conducted on circuits

that are de-energised. Ensure circuits are not

live before commencing testing.

-6-

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. The circuit is LIVE and should be de-

energised before further testing.

3. Press the TEST switch. 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 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.

1. Select the 20Ω range by rotating the FUNCTION

switch and connect the test leads to the

instrument. Short the tips of the test leads. Press

and hold down the TEST switch by twisting it

clockwise. The display will show the resistance of

the test leads. Adjust the Ω Null control to set the

reading to zero.

2. 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.

●AC voltage test:

Set the FUNCTION switch to ACV. Connect test

leads to circuit being measured. Press TEST switch

and read the value of voltage from the LCD.
