CAUTION!
Note on using the supplied safety test leads according the
IEC / EN 61010-031:2008:

Measurements in the field of overvoltage category CAT I or
CAT II can be performed with test leads without sleeves with a
maximum of up to 18mm long, touchable metallic probe,
whereas for measurements in the field of overvoltage category
CAT III or CAT IV test leads with put on sleeves, printed with
CAT III and CAT IV must be used, and therefore the touchable
and conductive part of the probes have only max. 4 mm of
length.

6. 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 20Ω range 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.
