SAFETY INSTRUCTIONS

This chapter contains important safety

instructions that you must follow during

operation and storage. Read the following before

any operation to insure your safety and to keep

the instrument in the best possible condition.

Safety Symbols

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

WARNING

Warning: Identifies conditions or practices that

could result in injury or loss of life.

CAUTION

Caution: Identifies conditions or practices that

could result in damage to the GPP or to other

properties.

DANGER High Voltage

Attention Refer to the Manual

Protective Conductor Terminal

Earth (ground) Terminal

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

Do not place any heavy object on the unit.

Avoid severe impact or rough handling that

leads to damaging the unit.

Do not discharge static electricity to the unit.

Do not block the cooling fan opening.

Do not perform measurements on circuits that

are directly connected to mains power.

Do not disassemble the GPP unless you are

qualified.

(Measurement categories) EN 61010-1:2010

specifies the measurement categories and their

requirements as follows. The GPP Series falls

under category I.

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.

Measurement category I is for measurements

performed on circuits not directly connected to

Mains.

Power Supply

WARNING

AC Input voltage range:

100V/120V/220V/230V ±10%

Frequency: 50Hz/60Hz

To avoid electrical shock connect the protective

grounding conductor of the AC power cord to

an earth ground.

GPP Series User Manual

Fuse

WARNING

Fuse type: 100V/120V：T6.3A/250V，

220V/230V：T3.15A/250V

To prevent fire, replace the fuse only with the

specified type and rating.

Disconnect the power cord before replacing the

fuse.

Make sure the cause of fuse blowout is fixed

before replacing the fuse.

Cleaning the

power supply

Disconnect the power cord before cleaning the

oscilloscope.

Use a soft cloth dampened in a solution of mild

detergent and water. Do not spray any liquid

into the oscilloscope.

Do not use chemicals containing harsh products

such as benzene, toluene, xylene, and acetone.

Operation

Environment

Location: Indoor, no direct sunlight, dust free,

almost non-conductive pollution (Note below)

Relative Humidity: < 80%

Altitude: < 2000m

Temperature: 0° C to 40° C

SAFETY INSTRUCTIONS

(Pollution Degree) EN 61010-1:2010 specifies

pollution degrees and their requirements as

follows. The GPP Series 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

Relative Humidity: < 70%

Temperature: -10° C to 70° C

GPP Series User Manual

Power cord for the United Kingdom

When using the power supply 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:

Neutral

Brown:

Live (Phase)

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 0.75mm2should 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.
