Introduction
Thank you for purchasing the HIOKI Model L2000 4-TERMINAL
PROBE. To obtain maximum performance from the device, please
read this manual first, and keep it handy for future reference.
Maintenance and Service
• To clean the device, wipe it gently with a soft cloth moistened with
water or mild detergent. Never use solvents such as benzene, alcohol, acetone, ether, ketones, thinners or gasoline, as they can
deform and discolor the case.
• If the device seems to be malfunctioning, contact your dealer or
Hioki representative.Pack the device so that it will not sustain damage
during shipping, and include a description of existing damage. We do
not take any responsibility for damage incurred during shipping.
Safety Information
This manual contains information and warnings essential for safe
operation of the device and for maintaining it in safe operating condition. Before using it, be sure to carefully read the following safety precautions.
This device is designed to comply with IEC 61010 Safety
Standards, and has been thoroughly tested for safety
prior to shipment. However, mishandling during use
could result in injury or death, as well as damage to the
device. However, using the device in a way not described
in this manual may negate the provided safety features.
Be certain that you understand the instructions and precautions in the manual before use. We disclaim any
responsibility for accidents or injuries not resulting
directly from device defects.
Safety Symbols
In the manual, the symbol indicates particularly important
information that the user should read before using the device.
The symbol printed on the device indicates that the user
should refer to a corresponding topic in the manual (marked with
the symbol) before using the relevant function.
Indicates DC (Direct Current).
The following symbols in this manual indicate the relative importance
of cautions and warnings.
Indicates that incorrect operation presents an extreme hazard
that could result in serious injury or death to the user.
Indicates that incorrect operation presents a significant hazard
that could result in serious injury or death to the user.
Indicates that incorrect operation presents a possibility of injury to
the user or damage to the device.
Indicates advisory items related to performance or correct operation of the device.
Operating Precautions
Follow these precautions to ensure safe operation and to obtain the full
benefits of the various functions.
Instrument Installation
Avoid the following locations that could cause an accident or damage to the
instrument.
Exposed to direct
sunlight
Exposed to high
temperature
Exposed to water, oil,
chemicals, solvents,
or other substances
Exposed to high humidity or condensation
Exposed to high levels
of particulate dust
To avoid electric shock, do not remove the device's case.
The internal components of the device carry high voltages and may become very hot during operation.
Do not attempt to modify, disassemble or repair the
device; as fire, electric shock and injury could result.
• Do not slant the device or place it on top of an uneven surface. Dropping or
knocking down the device can cause injury or damage to the device.
• To avoid damage to the device, protect it from physical shock when transporting and handling. Be especially careful to avoid physical shock from dropping.
• Keep the cables well away from heat sources, as bare conductors could be
exposed if the insulation melts.
For details on a device to be connected, refer to the instruction manual of the
device to be connected.

Names of Parts
Open and Short Compenstation
Perform open and short compensation to increase the measurement
accuracy.
For the detailed operating procedure, refer to the instruction manual of
the device to be connected.
Measurement Procedure
Clamp the clips at the tips of the probes onto the test sample and then
perform measurement.
Overview
The L2000 4-TERMINAL PROBE allows lead parts and other
measurement objects to be connected by cable and then measured. Various shaped parts can be measured with the four terminals.
Inspection and Maintenance
When you receive the device, inspect it carefully to ensure that
no damage occurred during shipping. If damage is evident, or if
it fails to operate according to the specifications, contact your
dealer or Hioki representative.
Preliminary Checks
• Before using the device for the first time, verify that it operates normally
to ensure that the no damage occurred during storage or shipping.
If you find any damage, contact your dealer or Hioki representative.
• Before using the device, make sure that the insulation on the probes
is undamaged and that no bare conductors are improperly exposed.
Using the device in such conditions could cause an electric shock,
so contact your dealer or Hioki representative for repair.

• Note that dirt on the contact surfaces of the electrodes and test sample may
result in a poor contact and the inability to perform measurement accurately.
• Open compensation and measurement of high impedance elements
are susceptible to the influence of externally induced noise and stray
capacitance, so we recommend using guarding; for example, connecting a metal plate to the GUARD terminal and carrying out the
compensation or measurement on the metal plate. (For details on
guarding, refer to the instruction manual of the connected device.)
• The probe tips are connected to the relay box by SMA connectors,
so correct measurement may not be possible if the SMA connectors
are not securely connected or if the wiring is incorrect.
