Definitions

POLLUTION (P) – addition of foreign matter solid, liquid or gaseous (ionized gases),

that may product a reduction of dielectric strength or surface resistivity.

• Degree 2 (P2) – only non-conductive pollution occurs except that
occasionally a temporary conductivity caused by condensation is

expected.

MEASUREMENT CATEGORY (CAT) – classication of testing and measuring circuit

according to the type of mains circuits to which they are intended to be connected.

• CAT II – measuring circuits connected to utilization points of the low-voltage
mains installation.

General Safety Information

To avoid personal injury and/or product damage, review and comply with the
following safety precautions. These precautions apply to both operating and
maintenance personnel and must be followed during all phases of operation, service,
and repair of this meter. Before applying power be sure to:

• Read and understand the safety and operational information in this manual.

• Apply all the listed safety precautions.

• Verify that the voltage selector on the back of the unit is set to the correct

line voltage. Operating the instrument at an incorrect line voltage will void the
warranty.

• Make all connections before applying power.

• Do not operate the instrument in ways not specied by this manual or by

Global Specialties.

Failure to comply with these precautions or with warnings elsewhere in this manual
violates the safety standards of design, manufacture, and intended use of the
instrument. Global Specialties assumes no liability for a customer’s failure to comply
with these requirements.

Dry Conditions

WARNING

Cleaning

CAUTION

measurements with dampness, or other environmental conditions

that might aect safety.

Hands, shoes, oor, and work bench must be dry. Avoid making

Use a soft cotton cloth lightly moistened with a mild solution of

detergent and water. Do not allow any portion to be submerged at
any time. Dry thoroughly before attempting to make measurements.
Do not use solvents or expose to solvent fumes as they may cause
deterioration or damage.

Do not Operate:

• In the presence of noxious, corrosive, ammable fumes, gases, vapors,

chemicals, or nely-divided particulates.

• In environments where there is a danger of any liquid being spilled on the

meter.

• In air temperatures exceeding the specied operating temperatures.

• In atmospheric pressures outside the specied altitude limits or where the

surrounding gas is not air.

Global Specialties

Only for use in pollution degree 2 environments where non-conductive pollution
occurs except occasionally when a temporary conductivity caused by condensation is
expected.

Electrical Power

CAUTION

This instrument is intended to be powered from a CATEGORY II
mains power environment. The mains power should be 115 VAC or
230 VAC (±10%) at 50/60 Hz. Use only the power cord supplied with
the instrument and ensure it is appropriate for your country of use.
Slide the switch on the back of the trainer to select the appropriate
input making sure the correct fuse is installed. This trainer consumes
less than 50 W.

Fuse Replacement

WARNING

Set the power switch to the OFF or O position and disconnect the
power cord before inspecting or replacing the fuse. Open the black

fuse holder (located at the back of the trainer below the input power

receptacle) with a small, at-head screwdriver. Remove the old fuse,

replace it with a new one, and reinstall the fuse holder. Use only 5 x 20
mm type T 1.5 A / 250 V or 0.75 A / 250 V Fuses.

Ground the Instrument

CAUTION

To minimize shock hazard, the instrument case must be connected to
an electrical safety ground. This instrument, and the chassis, is
grounded through the ground conductor of the supplied, three­conductor AC power cable per IEC 60320-1. Do not alter or bypass
the ground connection. Failure to use a properly-grounded approved
outlet and the recommended three-conductor AC line power cable
may result in injury or death. Unless otherwise stated, a ground
connection on the instrument’s front is for a reference of potential
only and is not to be used as a safety ground.

Indoor Use:

This instrument is intended to be used in an indoor pollution degree 2 environment.
The operating temperature range is 0 °C to 40 °C and the operating humidity range is
up to 80% relative humidity with no condensation allowed. Measurement results may

be outside specications if the instrument is used in non-oce-type environments.

Such environments may include rapid temperature or humidity changes, sunlight,
vibration and/or mechanical shocks, acoustic noise, electrical noise, strong electric

elds, or strong magnetic elds.

Do not Operate:

If the instrument is damaged, appears to be damaged, or if any liquid, chemical, or
other material gets on or inside the instrument, remove the instrument’s power cord,
remove the instrument from service, label it as not to be operated, and return the
instrument to Global Specialties for repair. Notify Global Specialties of the nature of
any contamination of the instrument.

Not for Critical Applications:

This instrument is not authorized for use in contact with the human body or for use as
a component in a life-support device or system.

Do not Touch Live Circuits

Do not Attempt Servicing:

WARNING

Instrument covers must not be removed by operating personnel.
Component replacement and internal adjustments must be made by

qualied service-trained maintenance personnel who are aware of

the hazards involved when the instrument’s covers and shields are
removed.

Under certain conditions, even with the power cord removed,
dangerous voltages may exist when the covers are removed. To
avoid injuries, always disconnect the power cord from the instrument,
remove all other connections (for example, test leads, probes, etc.),
discharge all circuits, and verify there are no hazardous voltages
present on any conductors by measurements with a properly­operating voltage-sensing device before touching any internal parts.
Verify the voltage-sensing device is working properly before and after
making the measurements by testing with known-operating voltage
sources and test voltages. Do not attempt any service or adjustment

unless another person capable of rendering rst aid and resuscitation

is present. Hazardous voltages may be present in unexpected
locations in circuitry being tested when a fault condition in the circuit
exists.
