Accuracy
We define measurement tolerances in terms of f.s. (full scale), rdg.
(reading) and dgt. (digit) values, with the following meanings:
f.s.
(maximum
display value or
scale lengt h)
rdg.
(reading or
displayed value)
dgt.
(resolution)
The maximum displayable value or scale
length. This is usually the name of the currently
selected range.
The value currently being measured and indicated on the measuring instrument.
The smallest displayable unit on a digital measuring instrument, i.e., the input value that
causes the digital display to show a "1" as the
least-significant digit.

Safety Notes
Measurement categories (Ove rvoltage categories)
Model 2301-20, 2302-20, 2303-20, 2304-20, 2304-21 and 2305-20
comply with CAT I safety requirements.
Model 2331-20 and 2332-20 comply with CAT III safety requirements.
To ensure safe operation of measurement ins truments, IEC 61010
establishes safety standards for various electrical environments,
categorized as CAT I to CAT IV, and calle d measurement categories. These are defined as follows.
CAT I Secondary electrical circuits connected to an AC electrical
outlet through a transformer or similar instrument.
CAT II Primary electrical circuits in equipme nt connected to a n AC
electrical outlet by a power cord (portable tools, household
appliances, etc.)
CAT II covers directly me asuring el ectrical outle t recept acles.
CAT III Primary electrical circuits of heavy equipment (fixed installa-
tions) connected directly to the distribution panel, and feeders
from the distribution panel to outlets.
CAT I V The circui t from the service d rop to t he service e ntrance, and
to the power meter and prim ary overcur ren t protec tion inst rument (distribution panel).

Higher-numbered categories correspond to electrical environments
with greater momentary energy. So a measurement instrument
designed for CAT III environments can endure greater momentary
energy than a instrument designed for CAT II.
Using a measurement instrument in an environment designated
with a higher-numbered category than that for which the instrument
is rated could result in a severe accident, and must be carefully
avoided.
Never use a CAT I measuring instrument in CAT II, III, or IV environments.
The measurement categories comply with the Overvoltage Categories of the IEC60664 Standards.

Notes on Use
Notes on Use
Follow these precautions to ensure safe operation and to obtain
the full benefits of the various functions.
Instrument Installation
Operating temperature and humidity: 0 to 50°C (32 to 122°F), 80%
RH (non-condensating)
Avoid the following locations that could cause an accident or damage to the instrument.
Exposed to direct
sunlight
Exposed to high
temperature
Exposed to liquids
Exposed to
high humidity or condensation
Exposed to high levels
of particulate dust
When the module is used in
a dusty environment, place it
in a dustproof case and take
measures to ensure heat
dissipation.
Do not allow the instrument to get wet, and do not take measurements with wet hands.
The instrument may be damaged.
In the presence of
corrosive or explosive
gases
Exposed to strong
electrom agnetic fields
Near electromagnetic
radiators
Subject to vibration
To avoid damage to the instrument, protect it from physical shock
when transporting and handling.
Be especially careful to avoid physical shock from dropping.
Do not obstruct the ventilation holes.
Ventilation holes for heat radiation are provided on the top and rear
panels of the instrument. Leave sufficient space around the ventilation
holes and install th e instrum ent wi th the ho les uno bstru cted. Installation
of the instrument with the ventilation holes obstructed may cause a
malfunction or fire.
When using the instrument in the case, drill ventilation holes.
Drill ventilation holes or install a ventilation fan to p revent heat buildup.

Notes on Use
Only use sensors dedicated to the type of module.
To avoid damaging the ins trument, do not connec t any other sensors
than those dedicated to the instrument to its input terminals. Furth er, do
not connect any other signal sources to the terminals, as such signals
may lead to module damage due to excessive voltage or current.

Wiring
• A qualified electrician shall perform the wiring to prevent
electric shock.
• Avoid live-line electrical work to prevent electric shock and
accidents due to short-circuiting.
• Ensure that the power supply, input, and output are correctly wired according to the wiring diagram. (See the section on "Preparations" for each module.) This will prevent
fire, malfunction, and errors.
Connect the module to a power source that matches the
rating in order to prevent fire.
• Do not work on live lines. Such work may result in electric
shock or short-circuiting.
• Use cables of the proper sizes for the rated current. This
will prevent entire system errors and fire resulting from
broken wire.
• Use crimp connectors suitable for the cable sizes. This will
prevent module errors and fire due to broken wires.
• When tightening the screws, confirm that all screws are
securely tightened. A loose screw may result in module
errors, fire, or electric shock.
• Tighten the screws within the s pecified torque. Excessive
torque may damage the terminals. Inadequate torque may
result in module errors, fire, or electric shock.

• Ensure that the power supply module and input are OFF
until all wiring work is finished. This will prevent module
trouble and electric shock.
• Ensure that the power supply module and input are OFF
when connecting or disconnecting the module to the system. This will prevent electric shock, errors, and malfunction.
• Avoid using an unused terminal for relaying or any other
purpose to prevent electric shock, errors, and malfunction.

Notes on Use
• If power supply noise poses a problem, use of a noise filter is
recommended.
• When the power and sig nal lines may be subject to a lightninginduced surge, install a lightning arrester between another
instrument or module connected to this module and line to protect the system.
• Avoid stepping on or pinching cables, which could damage the
cable insulation.
• Keep the cables well aw ay from heat sources, as bare conductors could be exposed if the insulation melts.
Preliminary Checks
Before using the instrument, make sure that the insulation
on the cables 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 repair.
To prevent an electric shock accident, confirm that the white or red portion (insulation layer) inside the cable is not exposed. If a color inside
the cable is exposed, do not use the cable.
Before using the instrument 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.

Cleaning
To clean the instrument, 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.

Never modify the instrument. Only Hioki service engineers
should disassemble or repair the instrument. Failure to
observe these precautions may res ult in fire, electric shock,
or injury.
• If the instrument seems to be malfunctioning, confirm that the
cables are not open circuited before contacting your dealer or
Hioki representative.
• When sending the instrument for repair, pack carefully to prevent
damage in transit. Include cushioning materia l so the instrument
cannot move within the package. Be sure to include details of the
problem. Hioki cannot be responsible for damage that occurs
during shipment.
• When transporting the module or a 2300 Smart Site, tape the
front of the module or take similar measures to avoid losing internal components.
• The instrument contains a built-in backup lithium battery, which
offers a service life of about five years. If the da te and time deviate substantially when the instrument is switched on, it is the time
to replace that battery. Contact your dealer or Hioki representative.

• Be sure to connect the cables to matching connectors to prevent
damage to the module or sensor.
Connect the 9764-50 HUMIDIDTY SENSOR to the module by following the procedure below.
1. Use a flat blade screwdriver to loosen the screws on the t ermi-
nal block.
2. Insert a cable into the terminal block, then tighten the screws
(at a tightening torque of 0.25 N•m).
3.
Connect the terminal block to the TEMP terminal, and HUM terminal.
• In case of external noise, wind the cable around the ferrite
