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.
AC Input voltage: 115V (+10% / -25%), AC

WARNING
Cleaning the LCR­8000G
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.
Do not use chemicals or cleaners containing

Storage environment
(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%
Disposal
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.

SAFETY INSTRUCTION
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.
or coloured
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.

Measurement tip
Hi/Low impedance
Metal component case connection
If the measured impedance is greater than 1kΩ, the standard four-terminal connection is not necessary. Run S/C trim to remove the effect of series lead impedance.
If the measured impedance is lower than 1kΩ, four-terminal connection can reduce the effect of contact resistance at the test component.
A large area of metal can add noise to the measurement. Here is how to minimize the effect.
If the metal is connected to one of the terminals, this should be connected to the Hforce (Yellow) terminal side.
If the metal is NOT connected to either of the terminals, connect the GND clip.
Small-sized capacitor
Small-sized inductor
When measuring small, SMD-size capacitors, run O/C trim at the measurement frequency (Spot trimming) to eliminate the residual capacitance. Make sure the measurement lead positions are fixed during trimming.
When measuring small, SMD-size inductors, run S/C trim at the measurement frequency (Spot trimming). The LCR-8000G measures the difference between the inductance of S/C trimming and the inductance of test component. Four-terminal fixture set is recommended and make sure the measurement leads are fixed during trimming.

Wire capacitance
Wire inductance
Frequency factor in inductor measurement
When measuring the wire capacitance, the fixture clips that are marked with H (High Sense)
should always be connected to the
(High Force)/HS
F
point that is influenced the most by noise.
The wire inductance should be subtracted from the measurement result.
5cm, 1mm diameter wire has 50nH inductance
5cm, 2mm diameter wire has 40nH inductance
When an inductor is measured at a frequency much lower than that for which it is designed (for example, an HF choke tested at AF), the inductor tends to behave as an inductive resistor. In these circumstances, measurement accuracy is widened by (1 + 1/Q) where Q is the quality factor.
Air-cored coils
Iron-cored and ferrite inductor
Air-cored coils can pick up noise very easily, therefore they should be kept well clear of any test equipment that may contain power transformers or display scan circuitry. Also, keep the coils away from metal objects which may modify inductor characteristics.
The effective value of iron-cored and ferrite inductors can vary widely with the magnetization and test signal level. Measure them at the AC level and frequency in use. When core materials are damaged by excessive magnetization (for example: tape heads and microphone transformers), check that the test signal is acceptable before connection.
