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.

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.

Background
When GROUND MODE is set to ON, the GPT9500 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
ground from the DUT side of the testing circuit
will not be measured. For this reason, this
testing mode is able to measure to a higher
resolution.
