HIOKI RM2612A961-02
Operating Precautions
Familiarize yourself with the separate document entitled “Operating Precautions” before using
the product and to observe the following precautionary information to ensure that the product can
be used safely and in a manner that allows it to perform as described in its specications. Use
of the product should conform not only to its specications, but also to the specications of all
accessories, options, and other equipment in use.
Installing the product
CAUTION
Do not place the product on an unstable or uneven surface. Doing so could cause the
product to fall or turn over, causing bodily injury or damage to the product.
This product 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.
Shipping precautions
Use the original product packaging when shipping the product. Store the packaging material after
opening the product.
CAUTION
To avoid damage to the product, avoid subjecting it to vibration or mechanical shock
during transport and handling. Exercise particular care to avoid subjecting the product
to mechanical shock, for example by dropping it.
Precautions related to use of the PC application CD
• Exercise care to keep the disc’s recording surface free of dirt and scratches. When writing text
and other information on the label surface, use a writing implement with a soft tip.
• Place the disc in a protective case and avoid exposure to direct sunlight as well as high
temperature and humidity.
• Hioki is not liable for any computer system issues arising from, or accompanying, use of this disc.

RM9004 Test Fixture (option)
HIOKI RM2612A961-02
• Do not touch the tips of the probes. When an object other than the measurement
target comes into contact with probes, they may be damaged.
• To avoid damaging the probes, always use the RM9004 Test Fixture in combination
with the RM9003 Press Unit. Use of the xture without the RM9003 Press Unit is
considered outside the scope of the product warranty.
IMPORTANT
• Always use the test xture case when storing or transporting the test xture.
• Electrode sheets that have been measured by the instrument cannot be used in production batteries due
to pressure marks left by the probes. Hioki is not liable for use of electrode sheets after measurement.

Overview
1.1 Product Overview and Features
The product comprises an electrode resistance measurement system that measures the composite
layer volume resistivity and interface resistance of electrode sheets used in lithium-ion batteries. Its
principal applications are research, development, and quality control.
New indicators for LIB electrode sheets: Quantifying composite layer resistivity and
interface (contact) resistance
The product isolates and quanties composite layer resistivity and interface resistance for LIB electrode
sheets. This information can be used in the evaluation of batteries in R&D and quality control to speed up
the development process.
Easy-to-understand display and simple measurement method
Simply move the cursor to a parameter to display guidance such as an explanation of the parameter and
the applicable input range. Additionally, you can isolate and calculate composite layer resistance and
interface resistance simply by placing the probes in contact with the surface of an electrode sheet and
making measurements.
Improved work efciency (automatic start function)
The instrument detects when the probes make contact with the sample and starts measurement,
eliminating the need to click [Start]. (This function is disabled by default.)
High level of safety
To prevent malfunctions caused by unintended operation, the RM9003 Press Unit has a lock lever. Probes
can be raised and lowered by pulling the lock lever forward.
1
Overview
Easy maintenance
Probes can easily be inspected and cleaned since the system is designed so that the tips of the probes
can be rotated to face forward without removing the RM9004 Test Fixture from the RM9003 Press Unit.
