SAFETY INSTRUCTION

This chapter contains important safety instructions that you must follow when operating or storing an LCR-8000G series LCR meter. Following these instructions will ensure your safety and keep the instrument in the best possible condition.

Safety Symbols

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

WARNING

CAUTION

Warning: Identifies conditions or practices that could result in injury or loss of life.

Caution: Identifies conditions or practices that could result in damage to the LCR-8000G or to other properties.

DANGER High Voltage

Attention Refer to the Manual

Protective Conductor Terminal

Earth (ground) Terminal

SAFETY INSTRUCTION

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 Guidelines

General Guideline

 Do not place any heavy object on the

instrument.

CAUTION

 Avoid severe impact or rough handling that

leads to damaging the instrument.

 Do not discharge static electricity to the

instrument.

 Do not block or obstruct the cooling fan vent

opening.

 Do not perform measurement at circuits directly

connected to Mains (Note below).

 Do not disassemble the instrument unless you

are qualified as service personnel.

(Measurement categories) EN 61010-1:2001 specifies the measurement categories and their requirements as follows. the LCR-8000G 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

Fuse

WARNING

Cleaning the LCR8000G

 AC Input voltage: 115V/230V, 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: T3A/250V

 Make sure the correct type of fuse is installed

before power up.

 To ensure fire protection, replace the fuse only

with the specified type and rating.

 Disconnect the power cord before fuse

replacement.

 Make sure the cause of fuse blowout is fixed

before fuse replacement.

 Disconnect the power cord before cleaning.

 Use a soft cloth dampened in a solution of mild

detergent and water. Do not spray any liquid.

Operation Environment

 Do not use chemicals or cleaners containing

harsh materials such as benzene, toluene, xylene, and acetone.

 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 INSTRUCTION

Storage environment

Disposal

(Pollution Degree) EN 61010-1:2001 specifies the pollution degrees and their requirements as follows. The LCR-8000G 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.

 Location: Indoor

 Relative Humidity: < 80%

 Temperature: −40°C to 70°C

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.

LCR-8000G Series User Manual

Power cord for the United Kingdom

When using an LCR-8000G series LCR meter 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

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.
