and their requirements as follows. The GPT-10000 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.

voltage, insulation resistance, ground bond and continuity safety
analyzers.
By and large, GPT-10000 Series has 2 major categories, one is GPT12XXX models, and the other is GPT-15XXX models. The subordinate
models of 2 categories share the same test functions but with different
specifications. We use the term “X” for the 2nd digit of model names
described below to stand for both 2 categories in common.
The GPT-1X001 is AC withstanding voltage and continuity tester,
the GPT-1X002 is AC/DC withstanding voltage and continuity
tester and the GPT-1X003 is AC/DC withstanding voltage,
insulation resistance and continuity tester. The GPT-1X004 includes
all the test functions of the other models, plus the ground bond
testing. See the following Lineup Overview for more details.
The GPT-10000 Series can store up to 100 manual tests, as well as
run up to 10 manual tests sequentially as an automatic test,
allowing the safety analyzers to accommodate any number of
safety standards, including IEC, EN, UL, CSA, GB, JIS and others.
Note: Throughout this user manual, the terms ACW, DCW, IR, GB
and CONT refer to AC Withstanding, DC Withstanding, Insulation
Resistance, Ground Bond and Continuity testing, respectively.

25
GPT-10000 Series User Manual
Background
The GPT-10000 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-10000 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 analyzer, lead wires,
terminals, probes and other connected
equipment when the tester is testing.
2. Do not turn the safety analyzer 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
26
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 analyzer unattended.
Always turn the power off when leaving the
testing area.
9. When remotely controlling the safety analyzer,
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-10000 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 analyzer before a
discharge is completed.
27
GPT-10000 Series User Manual
Background
The GPT-10000 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 analyzer is always connected
to an earth ground.
3. Test the safety analyzer operation with a low
voltage/current output:
Ensure the safety analyzer 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
When GROUND MODE is set to ON, the GPT10000 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 additional noise which 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 less noise will
be measured. For this reason, this testing mode
is able to measure with better stability.

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.

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
status, unlike under normal operation.
Separate settings can be saved under the special
test mode for each of the testing functions:
ACW, DCW, IR, GB and CONT. This means
different test setups for ACW, DCW, IR, GB
and CONT can be saved within the MANU
number 000 concurrently.
Steps
1. Choose MANU number 000 to
enter the special test mode.
Page 41
2. The settings of a previous test can
be loaded by pressing the
corresponding soft-keys on the

Sweep Function
Overview
The GPT-10000 Series has access to the sweep
mode function, which creates a graph of one of
the ACW, DCW, IR, GB or CONT tests in either
Manual test or the special MANU 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 fetched
and 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.
