Safety Guidelines
General Guideline
CAUTION
Make sure that the voltage input level does not
exceed AC600V.
Make sure the current input level does not
exceed 20A.
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 600Vpk.
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.
The device should be placed in a place where
the plug connected to it can be removed easily.

GPM-8310 User Manual

(Note) EN 61010-1:2010 specifies the measurement categories and
their requirements as follows. The GPM-8310 falls under category II
600V.
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.
If grounding practice is not well implemented, a
certain amounts of noises will be generated
when connecting to GPM-001, the handy
measurement accessory for GPM-8310.
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.
Operation
Environment
Location: Indoor, no direct sunlight, dust free,
almost non-conductive pollution (Note below)
Temperature: 0°C to 40°C
Humidity: < 30°C: < 80%RH(non-condensing);
30°C~40°C:<70%RH(non-condensing);
>40°C: <50%RH (non-condensing)
Altitude: <2000m
Overvoltage category: OVC II

SAFETY INSTRUCTIONS
9
(Note) EN 61010-1:2010 specifies the pollution degrees and their
requirements as follows. The GPM-8310 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.

Characteristics
The GPM-8310 is a high-precision, programmable power meter for
using in standby measuring the device with low power such as
switching power supplies, transformers, power supplies, adapter
and other devices. It equips with a color TFT-LCD screen and also
multiple graph displays which are very convenient for reading the
measurement results. The GPM-8310 has become a reliable power
measurement instruments because of its simple operation, excellent
performance, user-friendly graph displays and automatic
measurement interface.
Operation
Press the buttons on the front panel to easily
turn on the GPM-8310 measurement function.
All settings and measurements results are
displayed on the 5-inches TFT-LCD screen panel
for easy use of each function.
Standard display mode: 2 main measurement
results and 8 secondary measurement results are
displayed in this screen.
