SAFETY INSTRUCTIONS
This chapter contains important safety
instructions that you must follow during
operation and storage. Read the following before
any operation to ensure your safety and to keep
the instrument in the best possible condition.
Safety Symbols
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.

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-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
7
(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

GPT-9500 Series User Manual
8
(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
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-9500 Series Overview
Series lineup
The GPT-9500 Series are multi-channel AC/DC withstanding
voltage and insulation resistance safety tester.
The GPT-9513 is AC/DC withstanding voltage and insulation
resistance tester with 8 channels scan –Hi & Lo setup functions.
The GPT-9503 is AC/DC withstanding voltage and insulation
resistance tester with 8 channels scan –Hi setup functions.
For the all models, the testing terminals are also mirrored on the
rear panel for added safety and for more permanent safety testing
environments.
The GPT-9500 Series can store up to 501 manual tests, and run up
to 99 manual tests sequentially within an automatic test, allowing
the safety testers 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 and IR,
refer to AC Withstanding, DC Withstanding and Insulation
Resistance testing, respectively.
