Safety Notes
WARNING
This instrument is designed to conform to IEC
61010 Safety Standards, and has been thoroughly
tested for safety prior to shipment. However,
mishandling during use could result in injury or
death, as well as damage to the instrument. 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 instrument
defects.
Safety symbols
This manual contains information and warnings
essential for safe operation of the instrument and for
maintaining it in safe operating condition. Before
using the instrument, be sure to carefully read the
following safety notes.

Accuracy
We define measurement tolerances in terms of rdg.
(reading) values, with the following meanings:
rdg. (displayed or indicated value)
This signifies the value actually being measured,
i.e., the value that is currently ind icated or displayed
by the measuring instrument.
Measurement categories
To ensure safe operation of measurement
instruments, IEC 61010 establishes safety standards
for various electrical environments, categorized as
CAT II to CAT IV, and called measurement
categories. These are defined as follows.
CAT II: Primary electrical circuits in equipment
connected to an AC electrical outlet by a
power cord (portable tools, household
appliances, etc.)
CAT II covers directly measuring electrical
outlet receptacles.
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).
___________________________________________
Safety Notes
Page 49
___________________________________________
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.
Use of a measurement instrument that is not CATrated in CAT II to CAT IV measurement
applications could result in a severe accident, and
must be carefully avoided.

WARNING
Before using the instrument, make sure that the insulation
on the test leads and probes 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.
CAUTION
This device is intended solely for use with thermocouple
sensors (K type). To avoid damage, do not connect it to
any other type of sensor. Do not input a voltage signal
from the sensor terminal.
This instrument should be installed and operated indoors
only, between 0 to 40
operational temperature range for the temperature probe
is provided in the specifications given in Chapter 5.
The 3441, 3441-02 is not designed to be entirely water- or
dust-proof. To avoid damage, do not use it in a wet or
dusty environment.
Although this 3442 is designed to resist the ingress of
dust and water, it is not entirely water- or dust-proof, so
to avoid shock or damage, do not use it in a wet or dusty
environment.
Please be aware that direct contact of the instrument to oil
and other substances for a long period of time may cause
deformation of the case or damage to the instrument.
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.
The sheath of the temperature probe is filled with
magnesium oxide powder. If the probe is broken, the
magnesium oxide powder may spill out. Be carefulnot to
subject the sheath to excess stress. Inhaling large
quantities of magnesium oxide may be hazardous to your
health.

To avoid damage to the instrument, protect it from
vibration or shock during transport and handling, and
be especially careful to avoid dropping.
3.1 Preparations for the Batteries
WARNING
To avoid electrocution, turn off the power
switch and disconnect the probes before
removing the lithium battery. After replacing the
batteries, replace the lower case and screws
before using the instrument.
Do not mix old and new batteries, or different
types of batteries. Also, be careful to observe
battery polarity during installation. Otherwise,
poor performance or damage from battery
leakage could result.

WARNING
To avoid the possibility of explosion, do not
short circuit, disassemble or incinerate
batteries.
Handle and dispose of batteries in accordance
with local regulations.
CAUTION
To replace the battery, remove the lower case.
The lower case is secured with two screws. Take
care to avoid misplacing screws during battery
replacement.
The 3442 has rubber rings furnished in the lower
case and on the fastening screws. After removing
the lower case for battery replacement, make sure
the rubber rings are firmly in place before closing
the case. Improper seating of a rubber ring will
permit passage of moisture into the device and
damage it.
NOTE
To avoid corrosion from battery leakage, remove the
batteries from the instrument if it is to be stored for
a long time.

3.2 Connecting the Temperature Probe
CAUTION
The 9180, 9181, 9182, 9183, and 9476
temperature probes are not drip-proof. Water
droplets on the grip or connector may result in
malfunctions.
The 9472, 9473, 9474, and 9475 have a drip-proof
design. However, droplets occurring on the metal
terminal of the connector may cause measurement
errors.
The ends of the 9474 and 9475 sheath type
temperature probes are sharp. Be careful to avoid
injury.
To avoid breaking the probes, do not bend or pull
them.
When measuring high temperatures, do not let the
grip of the temperature probe or the compensation
lead wire exceed the temperature range (Chapter
5: Sensor (Options)).
The sheath of the temperature probe is filled with
magnesium oxide powder. If the probe is broken,
the magnesium oxide powder may spill out. Be
carefulnot to subject the sheath to excess stress.
Inhaling large quantities of magnesium oxide may
be hazardous to your health.
Connect the optional probe.
Check the polarity of the connector, and connect

If the instrument seems to be malfunctioning,
confirm that the batteries are not discharged, and
that the temperature probes are not open circuited
before contacting your dealer or Hioki
representative.
When sending the instrument for repair, remove
the batteries and pack carefully to prevent damage
in transit. Include cushioning material 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.
