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 INSTRUCTIONS

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.

 Interface: USB / RS232 / LAN2/ Mini GPIB

/Digital IO DA12 ports are only to be connected

to the circuits which are separated from mains

supply by double / reinforce insulation.

GPM-8320/8330 User Manual

(Note) EN 61010-1:2010 specifies the measurement categories and

their requirements as follows. The GPM-8320/8330 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.

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

(Note) EN 61010-1:2010 specifies the pollution degrees and their

requirements as follows. The GPM-8320/8330 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.
