safety prior to shipment. However, mishandling
during use could result in injury or death, as well as
damage to the product. 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
product defects.

Safety symbols

This manual contains information and warnings essential for
safe operation of the product and for maintaining it in safe
operating condition. Before using the product, be sure to
carefully read the following safety notes.

The symbol printed on the product indicates
that the user should refer to a corresponding
topic in the manual (marked with the

Measurement categories (Overvoltage categories)

This product conforms to the safety requirements for CAT I

measurement products.

To ensure safe operation of measurement products, IEC 61010

establishes safety standards for various electrical environments,

categorized as CAT I to CAT IV, and called measurement

categories. These are defined as follows.

CAT I : Secondary electrical circuits connected to an AC

electrical outlet through a transformer or similar device.

CAT II : Primary electrical circuits in equipment connected to an

AC electrical outlet by a power cord (portable tools,

household appliances, etc.)

CAT III : Primary electrical circuits of heavy equipment (fixed

installations) connected directly to the distribution panel,

and feeders from the distribution panel to outlets.

CAT IV : The circuit from the service drop to the service entrance,

and to the power meter and primary overcurrent

protection device (distribution panel).

Higher-numbered categories correspond to electrical environments

with greater momentary energy, so a measurement product

designed for CAT III environments can endure greater momentary

energy than one designed for CAT II. Using a measurement

product in an environment designated with a higher-numbered

category than that for which the product is rated could result in a

severe accident, and must be carefully avoided.

Never use a CAT I measuring product in CAT II, III, or IV

environments.

The measurement categories comply with the Overvoltage

Categories of the IEC60664 Standards.

Precautions

Follow these precautions to ensure safe operation and to

DANGER

WARNING

The floating voltage between input terminals and
ground is 450V DC/AC. Attempting to measure
voltages exceeding 450V with respect to ground
could damage the product and result in personal
injury.
When voltages higher than 30 Vrms, 42.4 Vpeak or
battery circuits with more than 60 VDC are to be
measured, be sure to establish the floating state
first. Carrying out such measurements in the
grounded state involves the risk of electric shock.
When measuring batteries, always ensure sufficient
ventilation. Sometimes sparks may occur when the
test leads are connected to batteries, which can
ignite any accumulated inflammable gases such as
hydrogen.
To avoid electric shock accidents, when measuring
batteries being charged wear proper protective gear
such as rubber gloves.

Do not allow the product to get wet, and do not take
measurements with wet hands. This may cause an
electric shock.
Do not use the product where it may be exposed to
corrosive or combustible gases. The product may be
damaged or cause an explosion.

Precautions

vi

___________________________________________________________________

WARNING

Before using the product, make sure that the
insulation on the leads is undamaged and that no
bare conductors are improperly exposed. Using the
product in such conditions could cause an electric
shock, so contact your dealer or Hioki representative
for replacements. (Model 9460)
Be sure to connect the SOURCE and SENSE
terminals (banana plugs), and TEMP SENSOR
terminal (mini-plug) correctly. See Section 4.2,
"Measurement" for details of the connections.
To avoid injury or damage to the product, do not
attempt to measure AC voltage, or DC voltage
exceeding 50 V.

50 VDC max.

Do not apply a voltage between the SOURCE(+) and
SENSE(+) or SOURCE(-) and SENSE(-) terminals.
This could result in damage to the unit.

CAUTION

This product is not designed to be entirely water- or
dust-proof. To avoid damage, do not use it in a wet or
dusty environment.

___________________________________________________________________

Precautions

___________________________________________________________________

vii

CAUTION

NOTE

Do not store or use the product where it could be
exposed to direct sunlight, high temperature or
humidity, or condensation. Under such conditions, the
product may be damaged and insulation may
deteriorate so that it no longer meets specifications.
Do not use the product near a device that generates a
strong electromagnetic field or electrostatic charge, as
these may cause erroneous measurements.

Use the specified 9460 CLIP TYPE LEAD WITH
TEMPERATURESENSORwhenthistesterisused.

Correct measurement may be impossible in the presence of
strong magnetic fields, such as near transformers and high­current conductors, or in the presence of strong
electromagnetic fields such as near radio transmitters.

Service

Before using the product 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.

When sending the product for repair, remove the batteries
and pack carefully to prevent damage in transit. Include
cushioning material so the product cannot move within the
package. Be sure to include details of the problem. Hioki
cannot be responsible for damage that occurs during
shipment.

Chapter 1

Overview

The 3550 is designed for measuring the internal resistance,
open-circuit voltage, and terminal temperature of secondary
batteries, including lead-acid batteries, nickel-cadmium
batteries, nickel-metal hydride batteries, and lithium-ion
batteries.

Features

Since it uses the AC four-terminal method to measure the
internal resistance, it provides accurate results with the lead
resistances and contact resistances eliminated.
It is possible to display the readings for the battery internal
resistance, voltage, and terminal temperature, without
changing functions. Moreover, a composite comparator
function, which can be set on resistance and voltage values,
enables reliable detection of battery deterioration.
The unit's memory function also allows a number of sets of
readings to be stored at a touch, and later output to a
printer.
These functions make this an ideal tool for checking
batteries which are under constant trickle charging and
cannot be disconnected.

NOTE

___________________________________________________________________

Measurements are taken by using noise reduction technology to

attenuate noise at frequencies other than the measurement

frequency (1 kHz). Incorrect measurements may result if a large

1-kHz noise component from the charger is present at the battery

terminals.
