NOTE: This lead/appliance must only be wired by competent persons
WARNING: THIS APPLIANCE MUST BE EARTHED
IMPORTANT: The wires in this lead are coloured in accordance with the
following code:
As the colours of the wires in main leads may not correspond with
the coloured marking identified in your plug/appliance, proceed
as follows:
The wire which is coloured Green & Yellow must be connected to
the Earth terminal marked with either the letter E, the earth symbol
or coloured Green/Green & Yellow.
The wire which is coloured Blue must be connected to the terminal
which is marked with the letter N or coloured Blue or Black.
The wire which is coloured Brown must be connected to the
terminal marked with the letter L or P or coloured Brown or Red.
If in doubt, consult the instructions provided with the equipment
or contact the supplier.
This cable/appliance should be protected by a suitably rated and
approved HBC mains fuse: refer to the rating information on the
equipment and/or user instructions for details. As a guide, a cable
of 0.75mm2 should be protected by a 3A or 5A fuse. Larger
conductors would normally require 13A types, depending on the
connection method used.
Any exposed wiring from a cable, plug or connection that is
engaged in a live socket is extremely hazardous. If a cable or plug is
deemed hazardous, turn off the mains power and remove the cable,
any fuses and fuse assemblies. All hazardous wiring must be
immediately destroyed and replaced in accordance to the above
standard.

Background
The GPT-9000/9000A is a high voltage
instrument that outputs dangerous voltages.
The following section describes precautions and
procedures that must be followed to ensure that
the tester is operated in a safe manner.
WARNING
The GPT-9000/9000A generates voltages of up to
5kVAC or 6kVDC. Follow all safety precautions,
warnings and directions given in the following
section when using the instrument.
1. Never touch the safety tester, lead wires,
terminals, probes and other connected
equipment when the tester is testing.
2. Do not turn the safety tester on and off quickly
or repeatedly. When turning the power off,
please allow a few moments before turning the
power back on. This will allow the protection
circuits to properly initialize.
Do not turn the power off when a test is
running, unless in an emergency.
3. Only use those test leads supplied with the
instrument. Leads with inappropriate gauges
can be dangerous to both the operator and the
instrument.
For GB testing, never use the Sense leads on the
SOURCE terminals.
4. Do not short the HIGH VOLTAGE terminal
with ground. Doing so could charge the chassis
to dangerously high voltages.
Operating Precautions
27
GPT-9000/9000A Series User Manual
5. Ensure the earth ground of the line voltage is
properly grounded.
6. Only connect the test leads to the HIGH
VOLTAGE/SOURCE H/SENSE H terminals
before the start of a test. Keep the test leads
disconnected at all other times.
7. Always press the STOP button when pausing
testing.
8. Do not leave the safety tester unattended.
Always turn the power off when leaving the
testing area.
9. When remotely controlling the safety tester,
ensure adequate safety measures are in place to
prevent:
Inadvertent output of the test voltage.
Accidental contact with the instrument during
testing. Ensure that the instrument and DUT are
fully isolated when the instrument is remotely
controlled.
10. Ensure an adequate discharge time for the
DUT.
When DCW or IR tests are performed, the DUT,
test leads and probes become highly charged.
The GPT-9000/9000A has discharge circuitry to
discharge the DUT after each test. The time
required for a DUT to discharge depends on the
DUT and test voltage.
Never disconnect the safety tester before a
discharge is completed.
28
GETTING STARTED
Background
The GPT-9000/9000A is a high voltage device
and as such, daily safety checks should be
made to ensure safe operation.
1. Ensure all test leads are not broken and are free
from defects such as cracks or splitting.
2. Ensure the safety tester is always connected to
an earth ground.
3. Test the safety tester operation with a low
voltage/current output:
Ensure the safety tester generates a FAIL
judgment when the HIGH VOLTAGE and
RETURN terminals are shorted (using the
lowest voltage/current as the testing
parameters).
WARNING
Do not use high voltages/currents when the HIGH
VOLTAGE and RETURN terminals are shorted. It
may result in damage to the instrument.

OPERATION
Background
The TIMER setting is used to set the test time
for the current test. The test time determines
how long the test voltage or current is applied
to the DUT. This test time does not include
Ramp , initial start time or discharge time
(note: GB does not have Ramp or discharge
times). The test time can be set from 0.5 seconds
to 999.9 seconds for ACW, DCW and GB and
1.0 second to 999.9 seconds for IR, with a
resolution of 0.1 seconds for all modes. The
timer can be turned off when in the special
MANU test mode when using the ACW or
DCW test functions.
Each test has an initial test time of
approximately 150ms and a discharge time
(except GB). The total discharge time depends
on the DUT and test voltage.

insulation, electrode gaps or other insulating
problems that cause temporary spikes in current
or voltage during ACW and DCW testing.
There are three ARC detection settings: OFF,
ON AND CONTINUE, ON AND STOP.
The ON AND CONTINUE setting will detect
arcs over the ARC current level and continue
the test, the ON AND STOP setting will stop the
test when an arc is detected.
ARC mode settings only apply to ACW and
DCW tests.
Steps
1. Press the UTILITY key on the front
panel when the tester is in EDIT

Background
When GROUND MODE is set to ON, the GPT9000/9000A grounds the return terminal to the
ground. This mode is best for DUTs that are
grounded to an earth ground by their chassis,
fixtures or operation environment. This mode
measures the potential of the HIGH VOLTAGE
terminal with respect to earth ground. This
means that any stray capacitance/resistance
that leaks to earth ground will also be
measured. This is the safest testing mode,
though potentially not as accurate.
When GROUND MODE is set to OFF, the
return terminal is floating with respect to the
earth ground. This mode is for DUTs that are
floating and not directly connected to an earth
ground. This is more accurate than when
GROUND MODE is set to ON as any stray
capacitance/resistance that leaks to the earth

Special Test
Mode Overview
When MANU number 000 is selected, the
special test mode is activated. Under the special
test mode, the voltage can be changed during a
test, in real time (ACW, DCW only). The test
function can also be changed when in READY
or VIEW status, unlike under normal operation.
Separate settings can be saved under the special
test mode for each of the testing functions:
ACW, DCW, IR and GB. This means a different
ACW, DCW, IR and GB test setup can be saved
for MANU number 000.
Sweep Function
Overview
The GPT-9901A/9902A/9903/9903A and 9904
have access to the sweep mode function. The
sweep function creates a graph of one of the
ACW, DCW, IR or GB tests in the special
manual mode. The graph will plot the output
voltage, current or resistance versus time. After
the test has been completed, the test current,
voltage or resistance at any point in time can be
viewed in the graph.
Below is an example of the resultant sweep plot
of a DCW test where a DC voltage is ramped
up to a user-defined level until the HI SET
current level has been tripped or the test time
runs out.
