Safety Guidelines
General Guideline
CAUTION
Make sure that the voltage input level does not
exceed DC989V/AC700V.
Make sure the current input level does not
exceed 25A.
Do not place any heavy object on the
instrument.
Avoid severe impact or rough handling that can
lead 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 or obstruct the cooling fan vent
opening.
Do not perform measurement at the source of a
low-voltage installation or at building
installations (Note below).
Do not disassemble the instrument unless you
are qualified as service personnel.
Make sure that the COM terminal to earth is
limited to 300Vpk.
Remove all test leads before disconnecting the
mains power cord from the socket.
If the equipment is used in a manner not
specified by the manufacturer, the protection
provided by the equipment may be impaired

(Note) EN 61010-1:2010 specifies the measurement categories and
their requirements as follows. The GPM-8213 falls under category II
300V.
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: 100~240 VAC 50/60Hz
The power supply voltage should not fluctuate
more than 10%.
Connect the protective grounding conductor of
the AC power cord to an earth ground, to avoid
electrical shock.
Fuse
WARNING
Fuse type: 2AT 100~240VAC
Make sure the correct type of fuse is installed
before power up.
To avoid risk of fire, replace the fuse only with
the specified type and rating.
Disconnect the power cord before fuse
replacement.
Make sure the cause of a fuse blowout is fixed
before fuse replacement.
Cleaning the
Instrument
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.

SAFETY INSTRUCTIONS

Operation
Environment
Location: Indoor, no direct sunlight, dust free,
almost non-conductive pollution (Note below)
Temperature: 0°C to 50°C
Humidity: < 30°C: < 80%RH(non-condensin
g
);
30°C~40°C:<70%RH(non-condensing);
>40°C: <50%RH (non-condensing)
Altitude: <2000m
(Note) EN 61010-1:2010 specifies the pollution degrees and their
requirements as follows. The GPM-8213 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: -40°C to 70°C
Humidity: <90%RH(non-condensing)
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.

Power cord for the United Kingdom
When using the unit in the United Kingdom, make sure the power
cord meets the following safety instructions.
NOTE: This lead/appliance must only be wired by competent persons
WARNING: THIS APPLIANCE MUST BE EARTHED
IMPORTANT: The wires in this lead are coloured in accordance with the
following code:
Green/ Yellow: Earth
Blue: Neutral
Brown: Live (Phase)
As the colours of the wires in main leads may not correspond with
the coloured marking identified in your plug/appliance, proceed
as follows:
The wire which is coloured Green & Yellow must be connected to
the Earth terminal marked with either the letter E, the earth symbol
or coloured Green/Green & Yellow.
The wire which is coloured Blue must be connected to the terminal
which is marked with the letter N or coloured Blue or Black.
The wire which is coloured Brown must be connected to the
terminal marked with the letter L or P or coloured Brown or Red.
If in doubt, consult the instructions provided with the equipment
or contact the supplier.
This cable/appliance should be protected by a suitably rated and
approved HBC mains fuse: refer to the rating information on the
equipment and/or user instructions for details. As a guide, a cable
of 0.75mm2should be protected by a 3A or 5A fuse. Larger
conductors would normally require 13A types, depending on the
connection method used.
Any exposed wiring from a cable, plug or connection that is
engaged in a live socket is extremely hazardous. If a cable or plug is
deemed hazardous, turn off the mains power and remove the cable,
any fuses and fuse assemblies. All hazardous wiring must be
immediately destroyed and replaced in accordance to the above
standard.
