GPT-10000 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-10000 unless you

are qualified.

Position
Guideline

WARNING

 The rear position of the GPT-10000 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-10000 when test is
underway. In addition, while test is ongoing,
never touch the device under test, the GPT­10000 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-10000.

Safety Guidelines

SAFETY INSTRUCTIONS

(Measurement categories) EN 61010-1:2010 specifies the
measurement categories and their requirements as follows. The
GPT-10000 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-10000

 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-10000 Series User Manual

(Pollution Degree) EN 61010-1:2010 specifies the pollution degrees
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.

Storage
environment

 Location: Indoor
 Temperature: -10°C to 70°C
 Relative Humidity: ≤ 85% (no condensation)

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.

GPT-10000 Series User Manual

Background

The GPT-12000 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-12000 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 safety analyzer.

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

24

GETTING STARTED

Background

The GPT-12000 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-12000 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

25

GPT-10000 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 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-12000 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.

26

GETTING STARTED

Background

The GPT-12000 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.
