These safety symbols may appear in this manual or on the
instrument.
WARNING
Warning: Identifies conditions or practices that
could result in injury or loss of life.
CAUTION
Caution: Identifies conditions or practices that
could result in damage to the instrument or to
other properties.
DANGER High Voltage

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.
Safety Guidelines
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 GPT-
10000 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 INSTRUCTIONS
7
(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

GPT-10000 Series User Manual
8
(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-12000 Series Overview
Series lineup
The GPT-12000 Series Safety Analyzers are AC/DC withstanding
voltage, insulation resistance, ground bond and continuity safety
analyzers.
The GPT-12001 is AC withstanding voltage and continuity tester,
the GPT-12002 is AC/DC withstanding voltage and continuity
tester and the GPT-12003 is AC/DC withstanding voltage,
insulation resistance and continuity tester. The GPT-12004 includes
all the test functions of the previous models, plus the ground bond
testing. Also, for the all the models, the testing terminals are also
mirrored on the rear panel for added safety and for more
permanent safety testing environments.
The GPT-12000 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.
