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
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 LCR-8000G or to
other properties.
DANGER High Voltage
Attention Refer to the 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 Guidelines
General
Guideline
CAUTION
 Do not place any heavy object on the
instrument.
 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
 AC Input voltage: 115V (+10% / -25%), AC
230V (+15% / -14%) (Selectable), 50/60Hz.
 Connect the protective grounding conductor of
the AC power cord to an earth ground, to avoid
electrical shock.

Fuse
WARNING
 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.
Cleaning the LCR-
8000G
 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 chemicals or cleaners containing
harsh materials 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

(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.
Storage
environment
 Location: Indoor
 Relative Humidity: < 80%
 Temperature: −40°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.

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 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.
