Safety Symbols

These safety symbols may appear in this manual or on the instrument.

GPM-8310 User Manual

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

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.

Safety Guidelines

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

(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.

Warning

 Do not use damaged device. Before using the

equipment, check its housing first to sure there is no any cracks. Do not operate this device in an environment containing explosive gases, steam or dust.

 The maximum measurable current and voltage are

600 V and 20A for voltage and current terminals of the rear panel of the GPM-8310. Do not input exceeded voltage and current, otherwise it will burn the device.

 The maximum input voltage are 10 V and 2V for

EXT1 and EX2 terminals of the rear panel of the GPM-8310. Do not input exceeded voltage, otherwise it will burn the device.

 Always use the supplied cable for connection.  Before connecting the device, observe all the safety

symbols marked on the device.

 Turn off the power to the device and the application

system before connecting I/O terminals.

 Do not install replacement parts on the device or

perform any unauthorized modifications.

 Do not use this device if the removable cover is

removed or loosened.

 Do not connect any cables and terminals before

performing self-test.

 Use only the power adapter supplied by the

manufacturer to avoid accidental injury.

 Do not use this device for life support systems or

any other equipment that has safety requirements.

Power Up

Steps

1. Ensure the AC voltage is 100~ 240V.

2. Connect the power

cord to the AC voltage input.

Note

Make sure the ground connector on the power cord is connected to a safety ground. This will influence the measurement accuracy.

3. Push to turn on the main

power switch on the front panel.

4. The display turns on and shows the last

function that was used before the power was reset.

2. Use up and down arrow keys to

select the desired range.

3. Press Enter button to confirm your

selection.

Available range

Crest Factor is 3:

AUTO, 5mA, 10mA, 20mA, 50mA, 100mA, 200mA, 0.5A, 1A, 2A, 5A, 10A, 20A

Crest Factor is 6/6A:

AUTO, 2.5mA, 5mA, 10mA, 25mA, 50mA, 100mA, 250mA, 0.5A, 1A, 2.5A, 5A, 10A

Note

When it is under the manual setting ranging from 5mA to 200mA, the manual range adjusts to auto range automatically if input current exceeds 700mA.

Note

When the measurement range is set manually, if the range status icon lights in green means that the measured value meets the setting range. On the contrary, If the range status icon lights in red means that the measured value doesn’t meet the best setting range. In this case. It is better to switch to other range to get more accurate measurement results.

Note

The P.I status icon lights in red when the current measurement circuit detects that the measured value exceeds setting range by 3 folds (CF is set to 3) or 6 folds (CF is set to 6/6A).
