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.

Overview
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 inuence 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.

Precautions for Measurement
3.6 Precautions for Measurement
Use in combination with BT3562 or BT3563
Contact check does not operate properly at 3000 Ω range. Also be aware that contact check cannot
be performed properly in the voltage function, either.
Use in combination with BT4560
Use the device with BT4560 for external trigger measurement or single measurement using the
:READ?
When using the device for internal trigger (free running), the life time of the relay is shortened as
the channel is switched during measurement (hot switching).
As the measurement current for BT4560 is 1.5 A (3 mΩ range), heat generation at the relay contact
becomes high. With heat generation, the thermoelectric power may become high.
command.
3
Use in combination with DM7275 or DM7276
If a measurement accuracy of a few µV is required, there is an effect by the thermoelectric power
due to coil heating of the channel relay. Minimize the close time of each channel to reduce this
effect as much as possible. Use single measurement using the
trigger and open the channel immediately after the measurement (heating from the relay coil is
controlled).
Measured value variation may be signicant when connected at the same time as the IM3590.
If you encounter this issue, enable the IM3590’s trigger synchronous output function.
:READ?
command or external
Use in combination with IM3590
Execute open correction and short correction to each channel you will use.
Error might occur to open correction and short correction due to high frequency. (Set the frequency
range you will correct when executing.)
Threshold value of the contact check might be larger than the setting.
Also, the inspection result of the contact state (the resistance value near the threshold) might vary.
Relay operation time and stability time
The relay open/close operation waits for a contact operation time (settling time). The settling time is
as follows.
Channel switching time
Channel Switching
Relay open settling time Relay close settling time
Settling time
Relay open Relay close Channel switching
5 ms 5 ms 11 ms
The relay contact operation is completed within the settling time, however, it may take some time
for the relay to be stabilized depending on the instrument to be used or measuring object. Set the
channel delay time or perform measurement after a sufcient delay time on the instrument.
Preventing relay contact welding
The relay contact may weld when relay switching is repeated with a large current owing (also
when the measuring object or instrument to be connected is capacitive). When relay contact
welding occurs, the measuring object may be shorted. Periodic inspection is recommended.
Reference: "Checking for relay contact welding" (p. 26)

Page 40
Precautions for Measurement
Inuence of thermoelectric power
Be aware of the thermoelectric power when a voltage accuracy of a few µV is required.
Install the device and instrument in a constant temperature environment and fully adjust them to the
ambient temperature before use.
Especially prevent uneven temperatures at the terminal.
When creating a measurement cable, use a connector and terminal of a material with low
thermoelectric voltage, such as brass (nickel plate), pure copper (+ gold plate), etc.
Exercise care to keep the contact surface clean.
High resistance and minute current measurement
In a high humidity environment, high resistance or minute current measurement may be affected by
leak current.
Do not touch the module board with your bare hand. Grease can cause leak current, which may
affect high resistance and minute current measurement.
Do not bundle the measurement cables when measuring minute current. Doing so may cause leak
current due to the capacity of the cables, resulting in an error in the measured value.
Caution regarding noise
Do not bundle the measurement cables or connection cables for the instrument and the power line.
Noise on the power line may cause malfunction of channel switching or an error in the measured
value.
When the measured value cannot be stabilized due to noise, connecting the ground (GND terminal)
of the device and the ground of the instrument may improve the condition.
Caution regarding load
When a load is applied to the measurement cable, the contact area of the connector becomes
unstable and the contact resistance is increased, which can cause the measured value to be
unstable.
When attaching the module to the main frame, be sure to secure the panel using screws. If the
panel cannot support the load when a vertical load is applied to the main frame, the module board
is stressed and may malfunction.

Channel Delay Function
3.7 Channel Delay Function
The delay time after channel switching can be specied. When the specied delay time elapses
after the channel relay is closed, a CLOSE signal of EXT. I/O is output.
If the measurement response time for the instrument needs to be ensured, set the delay time.
The required delay time depends on the instrument to be used and the measuring object.
Channel delay time setting example
Model Delay time
BT4560 1 ms
BT3562 10 ms
3561 3 ms
DM7276 0 ms
The channel delay time can be specied for each slot. The same delay time is used for all channels
within the slot.
For the switching sequence, see "3.4 Channel Switching Operation" (p. 31)

External Control (EXT. I/O)
Thoroughly read “Before starting the external control” (p. 6) beforehand.
Connecting the instrument and the EXT. I/O terminal allows you to perform measurement in
synchronization with channel switching when using the scan function. Also scan control can be
performed from the PLC and other devices.
All signals are isolated from the switching circuit, communication circuit, and ground (earth) (the
common terminal for I/O is shared).
The input circuit can be switched so that it can support sinking current output (NPN) or sourcing
current output (PNP).
Check the input/output rating and internal circuit conguration, and then understand the safety
precautions. After that, connect the instrument or control system and use it in a correct manner.

Communication Command Forwarding Function
8.6 Communication Command Forwarding Function
The communication command forwarding function forwards commands sent from the host to the
communication interface (RS-232C) of the instrument without making any change.
• It is possible to control both the device and instrument using one communication port.
• Commands are sent to the instrument in synchronization with the completion of channel switching
operation.
Data received from the instrument can also be forwarded in addition to sent data.

Response messages
When a query message is received, its syntax is checked and a response message is generated.
If an error occurs when a query message is received, no response message is generated for that
query.
Command syntax
Command names are chosen to mnemonically represent their function and can be abbreviated.
The full command name is called the “long form”, and the abbreviated name is called the “short
form”.
The command references in this manual indicate the short form in uppercase letters, extended to
the long form in lowercase letters, although the commands are not case-sensitive in actual usage.
:SYSTem:MODule:DELay
:SYSTEM:MODULE:DELAY
:SYST:MOD:DEL 0.01
:SYST:MOD:DELA 0.01
:SYST:MOD:DE 0.01
Response messages generated by the device are in long form and in uppercase letters.

Headers
Headers must always be prexed to program messages.
(1) Command program headers
The following three types are available.
Command type Example Description
Headers for simple
commands
Headers for compound
commands
Headers for standard
commands
ESE 0
*
:SYSTem:PRESet
RST
*
This header type is a sequence of letters and
digits.
These headers consist of multiple simple
command type headers separated by colons (:).
This header type begins with an asterisk (*),
indicating that it is a standard command dened
by IEEE 488.2.
(2) Query program headers
These commands are used to interrogate the instrument about the results of operations, measured
values, and the present states of instrument settings. As shown by the following examples, when
a query is formed by appending a question mark (?) after a program header, it is recognized as a
query.
Example:
STB?
*
:SYSTem:ERRor?

Page 77
Communication Method
Message terminators
This device recognizes the following message terminators (delimiters).
RS-232C CR, CR+LF
LAN CR, CR+LF
Depending on the interface settings, the following can be selected as the terminator for response
messages.
RS-232C CR+LF
LAN CR+LF
Reference: "Communication condition settings" (p. 61)
Separators
(1) Command program headers
Multiple messages can be written in one line by separating them with semicolons (;).
Example:
• When messages are combined in this way and if one command contains an error, all subsequent
messages up to the next terminator will be ignored.
• A query error occurs if a query command is combined with an immediately following semicolon (;)
and subsequent command.
(2) Header separator
In a message consisting of both a header and data, the header is separated from the data by a
space.
Example:
(3) Data separator
In a message containing multiple data items, commas (,) are required to separate the data items
from one another.
:ROUT:CLOSE 101;*OPC?
Semicolon
:SCAN:ADD 101

Communication Method
Data formats
The device uses character data and decimal numeric data depending on the command.
(1) Character data
Character data always begins with an alphabetic character, and subsequent characters may be
either alphabetic or numeric. Character data is not case-sensitive, although response messages
from the device are only upper case.
Like command syntax, the data can be in long or short form and can be received in either form.
Example:
(2) Decimal numeric data
Three formats are used for numeric data, identied as NR1, NR2, and NR3. Numeric values may
be signed or unsigned. Unsigned numeric values are handled as positive values.
Values exceeding the precision handled by the device are rounded to the nearest valid digit.
• NR1 integer data (example: +12, −23, 34)
• NR2 xed-point data (example: +1.23, −23.45, 3.456)
• NR3 oating-point exponential representation data (example: +1.0E-2, −2.3E+4)
The term “NRf format” includes all three of the above numeric decimal formats.
The device accepts NRf format data.
The format of response data is specied for each command, and the data is sent in that format.
Example:
:SYSTEM:MODULE:WIRE:MODE 1 WIRE2
:STAT:QUES:ENAB 106
:IO:PULSE:TIME 0.001
74
Page 79
Communication Method
Compound command header omission
For several commands having a common header are combined to form a compound command,
if they are written together in sequence, the common portion can be omitted after its initial
occurrence.
This common portion is called the “current path” (analogous to the path concept in computer le
storage), and until it is cleared, the interpretation of subsequent commands presumes that they
share the same common portion.
This usage of the current path is shown in the following example:
Full expression
:SYSTem:MODule:WIRE:MODE 1,WIRE2;:SYSTem:MODule:WIRE:MODE 2,WIRE2
Compacted expression
:SYSTem:MODule:WIRE:MODE 1,WIRE2;MODE 2,WIRE2
This portion becomes the current path and can be omitted from the messages immediately following.
The current path is cleared in the following circumstances.
• When the power is turned on
• Key reset
• A colon (:) is entered at the start of the command.
• Message terminator detection
Standard command messages can be executed regardless of the current path.
They have no effect upon the current path.
A colon (:) is not required at the start of the header of a simple or compound command. However,
to avoid confusion with abbreviated forms and operating mistakes, Hioki recommends to always
place a colon (:) at the start of a header.

Communication Method
Output queue and input buffer
Output queue
Response messages are stored in the output queue until read by the controller. The output queue
is also cleared in the following circumstances.
• When the power is turned on
• Query error
At a minimum, the device’s output queue can buffer a 64-byte response message.
When using the RS-232C interface, data in excess of that length may result in the output buffer
being cleared due to a query error.
When using the LAN or USB interface, query operation will enter a wait state once the buffer is full
and continue in that state until the data is received.
Input buffer
The input buffer can accommodate a minimum of 256 characters.
When using the RS-232C interface, data may be lost in the event of a buffer overrun.
When using the LAN or USB interface, operation will enter a wait state once the buffer becomes full
and continue in that state until the buffer is empty.

The Status Byte Register contains information about the event registers and the output queue.
Required items are selected from this information by masking with the Service Request Enable
Register. When any bit selected by the mask is set, bit 6 (MSS; the Master Summary Status) of
the Status Byte Register is also set, which generates an SRQ (Service Request) message and
dispatches a service request.

When any Status Byte Register bit enabled by the Service Request Enable Register has switched
from “0” to “1”, the MSS bit becomes “1”. Consequently, the SRQ bit is set to “1”, and a service
request is dispatched.
The SRQ bit is always synchronous with service requests, and is read and simultaneously cleared
