almost non-conductive pollution (Note below)

 Relative Humidity: ≤ 70% (no condensation)
 Altitude: < 2000m
 Temperature: 0˚C~40˚C

(Pollution Degree) EN 61010-1:2010 specifies the pollution degrees
and their requirements as follows. The GPT-9000 falls under degree

2.

Pollution refers to “addition of foreign matter, solid, liquid, or

gaseous (ionized gases), that may produce a reduction of dielectric
strength or surface resistivity”.

pollution occurs. The pollution has no influence.

 Pollution degree 2: Normally only non-conductive pollution

occurs. Occasionally, however, a temporary conductivity caused
by condensation must be expected.

 Pollution degree 3: Conductive pollution occurs, or dry, non-

conductive pollution occurs which becomes conductive due to
condensation which is expected. In such conditions, equipment
is normally protected against exposure to direct sunlight,
precipitation, and full wind pressure, but neither temperature
nor humidity is controlled.

Power cord for the United Kingdom

When using the safety tester in the United Kingdom, make sure the
power cord meets the following safety instructions.

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.

Workplace Precautions

23

GPT-9000 Series User Manual

Background

The GPT-9000 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 generates voltages of up to 5kVAC
or 6kVDC. Follow all safety precautions, warnings
and directions given in the following section when
using the GPT-9000.

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

24

GETTING STARTED

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 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.

25

GPT-9000 Series User Manual

Background

The GPT-9000 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 100ms and a
discharge time (except GB). The total discharge
time depends on the DUT and test voltage.

OPERATION

Background

ARC detection, otherwise known as flashover
detection, detects fast voltage or current
transients that are not normally detected. Arcing
is usually an indicator of poor withstanding
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 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

Warning

When GROUND MODE is set to OFF, the DUT,
fixtures or connected instrumentation cannot be
grounded. This will short circuit the internal
circuitry during a test.

For ACW and DCW tests, if it is not known whether
the DUT test setup is grounded or not, always set
GROUND MODE to ON.

Only set GROUND MODE to OFF when the DUT
is floating electrically.

Description

The Control settings are accessed in the
COMMON UTILITY menu. The Control
settings include: Start Control, Double Action,
Key Lock and Interlock.

Start Control is used to determine how a test is
started. Tests can be started via the front panel
(START/STOP buttons), from a remote
controller or via the SIGNAL I/O port.

The Double Action function is a safety feature
used to prevent accidentally starting a test.
Normally to start a test, the START button is
pressed when the tester is in the READY status.
To start a test when Double Action is ON, the
STOP button must first be pressed, followed by
the START button within 500ms.

Key Lock disables the front panel keys from
changing the test number, mode or testing
parameters. Only the Utility menu and any
keys required for testing are not disabled.

Control Settings

76

OPERATION

The Interlock function is a safety feature. The
interlock function prevents a test from running,
unless the interlock pins on the signal I/O port
connector are shorted. The included interlock
key can be used for this purpose. See page 102
for details.

Steps

1. Ensure the tester is in VIEW status.

Background

If all the test steps are allowed to run to
completion (the AUTO test is not stopped or a
protection setting is not tripped) then the tester
will judge each step as either PASS or FAIL.
This is shown as a table after the automatic test
has finished running.

Note

The PASS/FAIL judgment for an automatic test
depends on the results of all the steps (manual
tests) that compose the automatic test:

 Each step must be passed for a PASS judgment

(excluding skipped tests).

 A FAIL result for a single step will result in

FAIL for the whole automatic test.
