GPT-9500 Series User Manual
Do not dispose electronic equipment as unsorted
municipal waste. Please use a separate collection
facility or contact the supplier from which this
instrument was purchased.
General
Guideline
CAUTION
Do not place any heavy object on the
instrument.
Avoid severe impact or rough handling that
leads to damaging the instrument.
Do not discharge static electricity to the
instrument.
Use only mating connectors, not bare wires, for
the terminals.
Do not block the cooling fan opening.
Do not disassemble the GPT-9500 unless you are
qualified.
Position
Guideline
WARNING
The rear position of the GPT-9500 should be
placed in an area with easy accessible for power
disconnection, that is, unplugging the power
cord with ease.
Keep away from the device under test which
connects with the GPT-9500 when test is
underway. In addition, while test is ongoing,
never touch the device under test, the GPT-9500
as well as other relevant units.
Any inappropriate manner that is unspecified
by the manufacturer may result in irreversible
harms or impaired protection by the GPT-9500.

SAFETY INSTRUCTIONS
(Measurement categories) EN 61010-1:2010 specifies the
measurement categories and their requirements as follows. The
GPT-9500 does not fall under category II, III or IV.
Measurement category IV is for measurement performed at the
source of low-voltage installation.
Measurement category III is for measurement performed in the
building installation.
Measurement category II is for measurement performed on the
circuits directly connected to the low voltage installation.
Power Supply
WARNING
AC Input voltage range:
AC 100V – 240V ± 10%
Frequency: 50Hz/60Hz
To avoid electrical shock connect the protective
grounding conductor of the AC power cord to
an earth ground.
Cleaning the
GPT-9500
Disconnect the power cord before cleaning.
Use a soft cloth dampened in a solution of mild
detergent and water. Do not spray any liquid.
Do not use chemicals containing harsh material
such as benzene, toluene, xylene, and acetone.
Operation
Environment
Location: Indoor, no direct sunlight, dust free,
almost non-conductive pollution (Note below)
Relative Humidity: ≤ 70% (no condensation)
Altitude: < 2000m
Temperature: 0˚C~40˚C
7
GPT-9500 Series User Manual
(Pollution Degree) EN 61010-1:2010 specifies the pollution degrees
and their requirements as follows. The GPT-9500 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 degree 1: No pollution or only dry, non-conductive
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.
Storage

Location: Indoor
Temperature: -10°C to 70°C

Disposal
Do not dispose this instrument as unsorted
municipal waste. Please use a separate collection
facility or contact the supplier from which this
instrument was purchased. Please make sure
discarded electrical waste is properly recycled to
reduce environmental impact.

1. Under MANU test, press the EDIT
soft-key followed by pressing the
RAMP TIME soft-key to enter the
parameter field.
2. The selected parameter (RAMP)
will be underlined in orange. Use
the scroll wheel to increase or
decrease the value.
3. Use the arrow keys to move the
cursor to a target digit of the
desired value.
4. Turn the scroll wheel again to edit

Background
The GPT-9500 is a high voltage instrument that
outputs dangerous voltages. The following
section describes precautions and procedures
that must be followed to ensure a safe work
environment.
WARNING
The GPT-9500 generates voltages in excess of
5kVAC or 6kVDC. Follow all safety precautions,
warnings and directions given in the following
section when using the instrument.
1. Only technically qualified personnel should be
allowed to operate the hipot tester.
2. The operating workplace must be fully isolated,
especially when the instrument is in operation.
The instrument should be clearly labeled with
appropriate warning signage.
3. The operator should not wear any conductive
materials, jewelry, badges, or other items, such
wrist watches.
4. The operator should wear insulation gloves for
high voltage protection.
5. Ensure the earth ground of the line voltage is
properly grounded.
6. Ensure any devices that are adversely affected
by magnetic fields are not placed near the
tester.
Workplace Precautions
27
GPT-9500 Series User Manual
Background
The GPT-9500 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-9500 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 hipot tester, lead wires,
terminals, probes and other connected
equipment when the tester is testing.
2. Do not turn the hipot 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.
4. Do not short the HIGH VOLTAGE terminal
with ground. Doing so could charge the chassis
to dangerously high voltages.
5. Ensure the earth ground of the line voltage is
properly grounded.
Operating Precautions
28
GETTING STARTED
6. Only connect the test leads to the HIGH
VOLTAGE 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 hipot tester unattended.
Always turn the power off when leaving the
testing area.
9. When remotely controlling the hipot 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-9500 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 hipot tester before a
discharge is completed.
29
GPT-9500 Series User Manual
Background
The GPT-9500 tester 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 tester is always connected to an
earth ground.
3. Test the tester operation with a low
voltage/current output:
Ensure the 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.
