WARNING
•
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.
•
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.

Environment
•
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
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%

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

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 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.

Metal component

Small-sized

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.
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.

measurement
Air-cored coils
Iron-cored and
ferrite inductor
When measuring the wire capacitance, the fixture
clips that are marked with HF(High Force)/HS
(High Sense) should always be connected to the
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 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.
BASIC MEASUREMENT
Basic measurement measures DUT in numerical
style. Advanced measurements are available in
Pass/Fail test mode (page58), where measurement
results are compared with user-defined limits, and
in Graph mode (page87), where measurement
data is displayed in graphical representation.
In general, two items, primary and secondary, are combined in a
single measurement. The following table shows the available
combinations. Overview of each measurement item is listed from

O/C trimming
Calibration (trimming) eliminates stray

fixture. It is required when using the instrument in
a new environment, or using a new set of testing
fixtures.
The testing fixture clips are separated by a distance

FAQ
Q1. The beep keeps sounding.
A1. The beep sounds according to the pass/fail test result, which in
this case is set to repetitive mode. Do one of the following.
•
Set the test mode to Single (manual trigger), so that the beep
sounds only when the test is initiated manually. Press the
Sing/Rep key to change the setting. For details, see page55.
•
Turn Off the beep entirely. Press the Menu key, F5 (System),
move the cursor to Beep and select Off using the arrow keys. For
details, see page61.
Q2. Panel operation seems disabled.
A2. Panel (local) operation is disabled in the Remote control mode
(page107). Press the Local key to bring back the instrument to local
operation mode (remote control is cancelled).
Q3. I cannot see the display clearly.
A3. Use the display contrast knob on the rear panel to adjust the
brightness.
