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 indicated 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
___________________________________________
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 CAT-
rated in CAT II to CAT IV measurement
applications could result in a severe accident, and
must be carefully avoided.

Notes on Use
Follow these precautions to ensure safe operation and
to obtain the full benefits of the various functions.
Setting up the Instrument
Operating temperature and humidity:
0to40 ° C(32 ± 122 ° F), 80%RH or less (non-condensating)
Temperature and humidity range for guaranteed accuracy:
23 ± 5 ° C(73 ± 9 ° F), 80% RH or less (non-condensating)
Preliminaly Checks
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.

___________________________________________
Notes on Use
___________________________________________
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 (32 to 104 ) and 80% RH. The
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.
