WARNING

Fuse

WARNING

(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.

 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 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

6

 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.

 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.

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:
Brown:

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 0.75mm

2

should 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.

Operation

 Press the buttons on the front panel to easily

turn on the GPM-8213 measurement function.
All settings and measurements results are
displayed on the TFT-LCD screen panel for easy
use of each function.

 Standard display mode: 2 main measurement

results and 6 secondary measurement results are
displayed in this screen.

 Simple display mode: 4 major measurement

results are displayed in this screen.

Characteristics

The GPM-8213 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 which is
very convenient for reading the measurement results. The GPM­8213 has become a reliable power measurement instruments
because of its simple operation, excellent performance and
automatic measurement interface.
