Safety Information
Safety Information
Be sure to also read the separate document “Operating Precautions” before use.
Usage Notes
Check before use
Follow these precautions to ensure safe operation and to obtain the full benets of the various
functions.
WARNING
If a connection cable or the device is damaged, there is a risk of an electric shock.
Perform the following inspection before using the device.
•Before using the device, check that the coating of the connection cables are
neither ripped nor torn and that no metal parts are exposed. Using the device
under such conditions could result in an electric shock. Replace any damaged
cable with a new one.
•Before using the device the rst time, verify that it operates normally to ensure
that no damage occurred during storage or shipping. If you nd any damage,
contact your authorized Hioki distributor or reseller.
This device is designed to measure voltages of 60 V or lower. Do not input
voltages over 60 V or measure locations exceeding 60 V from the ground potential.
If the relay of the device fails, the battery of the measuring object may be shorted
(p. 145).
Installing the device and module
CAUTION
Do not position the device on an unstable table or inclined surface. Dropping or
knocking down the device can cause injury or damage to the device.
Installing
To prevent overheating, be sure to leave the specied clearances around the device.
•The device should be operated only with the bottom side downwards.
Rear: 10 mm or moreSide: 50 mm or more

Usage Notes
Handling the device
This device may cause interference if used in residential areas. Such use must be avoided unless
the user takes special measures to reduce electromagnetic emissions to prevent interference to the
reception of radio and television broadcasts.
Before installing the module
WARNING
•To prevent an electric shock, before removing or replacing a module, conrm
that the device is turned off and that all the measurement cables, connection
cables, and the power cord are disconnected.
•Installing a module while the device is turned on may prevent detection of
the contact state of relays on the module or result in short-circuiting of the
measuring object. Damage of the device or module may cause the measuring
object to be shorted or the instrument to fail.
•Be careful about short circuits when connecting a measuring object with
electromotive force (battery, power supply, etc.).
•The maximum voltage of the device contact is 30 V (rms value) and 42.4 V (peak
value) or 60 V (direct current). Do not directly connect a withstand voltage tester
or an insulation resistance tester.
CAUTION
When installing or removing the module, be sure to observe the following precautions:
•Touch the GND terminal of the device with your hand to release static and then use
antistatic gloves to perform procedures.
•Hold the sheet metal area of the module. Directly touching the board with your hand may
damage the circuit board due to static. If the measurement target has high resistance, the
error component due to factors such as oil from your ngers may increase in magnitude.
Before measurement
DANGER
• Do not short-circuit between electrodes or terminals using a probe when
measuring the battery or capacitor. Doing so may cause an electric arc, resulting
in serious injury.
•Do not use the device or the connection cables that exceed its ratings or
specications. Doing so may damage the device or cause it to become hot,
resulting in a bodily injury.
•Do not use the instrument to be used in conjunction with the device outside of
its ratings or specications. Doing so may damage the instrument or cause it to
become hot, resulting in a physical injury.
WARNING
The maximum rated voltage between the module and ground is 60 V DC. To avoid
an injury and damage to the device, ensure that voltage between channels never
exceeds this limit. Prevent the voltage potential difference of the entire system
from exceeding 60 V DC.
The measurement connector frame of the module is connected to the casing (metal) of the device
as well as the protective ground terminal of the power inlet (conductive).

Usage Notes
Before starting the external control
WARNING
To prevent an electric shock or damage to the device, always observe the
following precautions when connecting the cables to the EXT. I/O terminals.
•Always turn off the device and any devices to be connected before making
connections.
•Be careful to avoid exceeding the signal ratings of the EXT. I/O terminals.
•During operation, a wire becoming dislocated and contacting another
conductive object can be a serious hazard. Use screws to secure the external
connectors.
•Ensure that devices and systems to be connected to the EXT. I/O terminals are
properly isolated from one another.
Before connecting the communications cables
CAUTION
•Use a common ground for both the device and the PC. Using different ground circuits
will result in a potential difference between the device's ground and the computer's
ground. If the communications cable is connected while such a potential difference
exists, it may result in device malfunction or failure.
•Before connecting or disconnecting any communications cables, always turn off the
device and the PC. Failure to do so could result in equipment malfunction or damage.
•After connecting the communications cables, tighten the screws on the connector
securely. Failure to secure the connector could result in device malfunction or damage.
•To avoid device failure, do not disconnect the communications cables while
communications are in progress.
Precautions during shipment
Store the packaging in which the device was delivered, as you will need it when transporting the
device.
Disc precautions
•Exercise care to keep the recorded side of discs free of dirt and scratches. When writing text on
a disc’s label, use a pen or marker with a soft tip.
•Keep discs inside a protective case and do not expose to direct sunlight, high temperature, or
high humidity.
•Hioki is not liable for any issues your computer system experiences in the course of using this
disc.

1Overview
1.1 Overview of Product
This device is a module type switching system that is ideal for multi-channel measurement of
batteries. You can choose a main frame from two choices according to the required number of
channels. You can also choose a module from two module types according to the instrument to be
used with the device (2-wire/4-wire module and 4-terminal pair module).
1.2 Features
Reduction of errors when measuring internal resistance
When AC low resistance measurement is performed using the BT4560 Battery Impedance Meter
or the BT3562 Battery HiTester, the inuence of electromagnetic induction (eddy current) on the
measured value can be minimized.
Ability to switch measurement between two instruments
For example, you can connect a BT3562 and DM7276 to the device and use it to switch between
internal resistance measurement and high-precision OCV measurement.
Protection against short circuit with fuses
To protect batteries to be measured if a short circuit occurs in a channel, a protective fuse is built
into each channel.
