2. SAFETY INSTRUCTIONS

This chapter contains important safety instructions that should be followed when operating and storing the oscilloscope. Read the following before any operation to ensure your safety and to keep the oscilloscope in the best condition.

Safety Symbols

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

Warning: Identies conditions or practices that could result in injury or loss of life.

WARNING

Caution: Identies conditions or practices that could result in damage to the

oscilloscope or to other objects or property.

CAUTION

DANGER High Voltage

Attention: Refer to the Manual

Protective Conductor Terminal

Earth (Ground) Terminal

Safety Guidelines

General Guideline

• 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 re and electric shock.

• Do not place heavy objects on the oscilloscope.

• Avoid severe impact or rough handling that may damage the oscilloscope.

• Avoid discharges of static electricity on or near the oscilloscope.

• Use only mating connectors, not bare wires, for the terminals.

• Do not block the cooling fan vent.

• Do not perform measurements at power sources and building installation sites

(Note below).

• The oscilloscope should only be disassembled by a qualied technician.

(Measurement categories) EN 61010-1:2001 species the measurement

categories and their requirements as follows. The unit falls under category II.

• Measurement category IV is for measurement performed at the source of a low-voltage installation.

• Measurement category III is for measurement performed in a building installation.

• Measurement category II is for measurement performed on circuits directly connected to a low voltage installation.

• Measurement category I is for measurements performed on circuits not directly connected to Mains.

Power Supply • AC Input voltage: 100 ~ 240V AC, 47 ~ 63Hz

WARNING

Fuse • Fuse type: T1A/250V

• The power supply voltage should not uctuate more than 10%.

• Connect the protective grounding conductor of the AC power cord to an earth

ground.

• To ensure re protection, replace the fuse only with the specied type and

rating.

• Disconnect the power cord before replacing the fuse.

• Make sure the cause of fuse blowout is xed before replacing the fuse.

Cleaning the oscillo-scope

Operation Environment

• 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.

• Location: Indoor, no direct sunlight, dust free, almost non-conductive pollution (Note below)

• Relative Humidity: ≤ 80%, 40°C or below

≤ 45%, 41°C~50°C

• Altitude: < 2000m

• Temperature: 0°C to 50°C

(Pollution Degree) EN 61010-1:2001 species pollution degrees and their

requirements as follows. The oscilloscope 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 inuence.

• 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, nonconductive 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

• Storage Temperature: -10°C~60°C, no condensation

• Relative Humidity: 93% @ 40°C

65% @ 41°C ~60°C

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 identied 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

0.75mm2 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.
