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 safety symbols may appear in this manual or on the GDS-

3000.

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 GDS-3000 or to other properties.

DANGER High Voltage

Attention Refer to the Manual

Protective Conductor Terminal

Earth (ground) Terminal

GDS-3000 Series 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

Safety Guidelines

General Guideline

CAUTION

 Make sure the BNC input voltage does not

exceed 300V peak.

 Never connect a hazardous live voltage to the

ground side of the BNC connectors. It might lead to fire and electric shock.

 Do not place any heavy object on the GDS-3000.  Avoid severe impact or rough handling that

leads to damaging the GDS-3000.

 Do not discharge static electricity to the GDS-

3000.

 Use only mating connectors, not bare wires, for

the terminals.

 Do not block the cooling fan opening.  Do not perform measurement at a power source

or building installation site (Note below).

 Do not disassemble the GDS-3000 unless you

are qualified.

(Measurement categories) EN 61010-1:2001 specifies the measurement categories and their requirements as follows. the GDS-3000 falls under category II.

 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: 100 ~ 240V AC, 48 ~ 63Hz,

auto selection

 Connect the protective grounding conductor of

the AC power cord to an earth ground, to avoid electrical shock.

GDS-3000 Series User Manual

Cleaning the GDS-3000

 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 chemical 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)

 Relative Humidity: < 80%  Altitude: < 2000m  Temperature: 0°C to 50°C

(Pollution Degree) EN 61010-1:2001 specifies the pollution degrees and their requirements as follows. The GDS-3000 falls under degree

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: -20°C to 70°C

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.

SAFETY INSTRUCTIONS

Power cord for the United Kingdom

When using the oscilloscope 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 0.75mm

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.
