instruction manual.
WARNING, DANGER OF ELECTRICAL SHOCK
In order to avoid electrical shock, the valid safety and national regulations
regarding excessive contact voltages must receive utmost attention when
working with voltages exceeding 120V DC or 50V RMS AC.
The respective accident prevention regulations established by the national
health & safety board for electrical systems and equipment must be strictly
met at all times.
Prior to any operation, ensure that the instrument, test leads, mains cable
and accessories are in perfect condition.
The instrument may only be connected to mains voltage as indicated in the
technical specification section.
The instrument may only be used within the operating ranges as specified in
the technical specification section.
Only touch test leads and test probes at handle area provided. Never directly
touch test probes. Direct contact to measurement connectors or test probes
must be avoided at any time.
The instrument may only be used in dry and clean environments. Dirt and
humidity reduce insulation resistance and may lead to electrical shocks, in
particular for high voltages.
Never use the instrument in precipitation such as dew or rain. In case of
condensation due to temperature jumps, the instrument may not be used.
A perfect display of measurement values may only be ensured within the
temperature range of 0 °C to +40 °C.
Prior to opening the instrument ensure that it is switched off and
disconnected from all current circuits.
To ensure a safe measurement only use original test leads and accessories.
If the operator’s safety is no longer guaranteed, the instrument is to be put
out of service and protected against use. The safety can no longer be
guaranteed if the instrument (or test leads):
– shows obvious damage
– does not carry out the desired measurements
– has been stored for too long under unfavourable conditions
– has been subjected to mechanical stress during transport.
Dangerous voltages may be present on appliances or device under test (DUT)
caused by insulation test. Do not touch the appliances under test, danger of
electrical shock!
Start any test series by protective bonding resistance measurement.
At protective bonding resistance test, insulation test and substitute leakage
test, unit under test must be voltage-free. If necessary check the unit is
voltage-free i.e. by using a voltage tester.
Accidental measurement of a defective unit may trip an RCD (residual
current device).

Testing Appliances
WARNINGS
Before commencing any testing you are strongly advised to make reference to
the local regulations and standards for safety at works regulations and any
relevant publications from the Health and Safety Executive.
The appliance must be switched on for all tests.
When conducting tests do not touch the appliance as some tests involve high
voltages and high currents.
16
GT-600/GT-800 Instruction Manual
The tests should only be performed by competent persons who are familiar
with the requirements of the type of tests suitable for portable appliances.
It is potentially hazardous for both user and appliance should the wrong type
of tests be undertaken or if testing is carried out in an incorrect sequence.
It is important that you fully understand the various tests required and how
they should be performed.
The appliance must have passed the visual inspection, the protective bonding
resistance test (class I), and the insulation test (in this sequence) prior to any
other test. If any of these fail further testing must be stopped and any faults
must be rectified.
During the protective conductor current test, the touch current test and the
load test, the appliance will be energized at mains voltage. For this purpose,
switch on the appliance. Appliances driven by motors or equipped with
heating units may present a danger for the person testing (comply with the
appliance instruction manual!). Please ensure that the appliance is in a safe
condition to run and secure prior to testing.
Visual Inspection
Visually inspect the appliance before starting electrical tests.
Check the appliance for the following:
Condition of the appliance cables, i.e. no cuts, cracks or any physical damage
to the outer insulation layer.
Condition of the plug, cable securely attached, no signs of overheating and
that fitted fuses are correctly rated.
Any signs of damage, and that any mains or control switches will physically
switch on and off.
Any sockets for sign of overheating or physical damage.

Insulation Resistance Test 250 V / 500 V (RISO)
The insulation resistance test measures the resistance of the insulation between:
L/N terminals of test socket and PE terminal of test socket in parallel with
PROBE 2 (at class I and class II). L/N terminals are shorted by the tester for this
test.
Test probe PROBE 1 and test probe PROBE 2 (at class III).
Warnings
The test voltage is either 500 V (or 250 Vd.c. at GT-800 only). Do not
touch the appliance during the insulation test! If the test fails, any metal
part of the appliance could become live!
Always make sure that the test has completed before disconnecting the
appliance leads to ensure that all capacitances have discharged!
Cautions
Do not perform the Insulation test on appliances that failed the
protective bonding test or the visual inspection test.
The insulation test may not be suitable for some types of appliances. For
these appliances an alternative test may be conducted such as touch
current, protective conductor current or substitute leakage current test.
It is essential to refer to the local appliance test standards and/or
reference material for the safe applicability of these alternative tests.
Test voltage of 500 V may not be suitable for some appliances that
contain overvoltage protection devices (e.g. varistors) in its installation.
For these appliances test voltage of 250 V shall be used, refer to the
local appliance test standards and/or follow the manufacturer
recommendations.
Remarks:
Connect the appliance and the test lead according to the figure 9, 10 or 11.
For class I appliances no probe is required except if there are some metal
parts on the appliance which are not connected to PE terminal.
For class II appliances apply the test probe to any exposed metalwork on the
