Thank you for purchasing the HIOKI "3447-01
TEMPERATURE HiTESTER". To obtain maxi-
mum performance from the product, please read
this manual first, and keep it handy for future refer-
ence.
• When you receive the product, inspect it carefully
to ensure that no damage occurred during ship-
ping. In particular, check the accessories, panel
switches, and connectors. If damage is evident, or
if it fails to operate according to the specifications,
contact your dealer or Hioki representative.
• Before using the product, make sure that the insu-
lation on the 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 rep-
resentative for repair.
• 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 representa-
tive.

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 fol-
lowing safety notes.
Safety Symbols
Safety Notes
This product is designed to conform to IEC
61010 Safety Standards, and has been thor-
oughly tested for 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 man-
ual before use. We disclaim any responsibil-
ity for accidents or injuries not resulting
directly from product defects.
In the manual, the symbol indicates particu-
larly important information that the user should
read before using the product.
The symbol printed on the product indicates
that the user should refer to a corresponding topic
inthemanual(markedwiththe symbol)before
using the relevant function.
Indicates DC (Direct Current).

The following symbols in this manual indicate the
relative importance of cautions and warnings.
Other Symbols
Accuracy We define measurement tolerances in terms of
rdg. (reading) and dgt. (digit) values, with the fol-
lowing meanings:
Indicates that incorrect operation presents an ex-
treme hazard that could result in serious injury or
death to the user.
Indicates that incorrect operation presents a sig-
nificant hazard that could result inserious injury or
death to the user.
Indicates that incorrect operation presents a pos-
sibility of injury to the user or damage to the prod-
uct.
Advisory items related to performance or correct
operation of the product.

Measurement categories (Overvoltage categories)
This product conforms to the safety requirements
for CAT I measurement products.
To ensure safe operation of measurement prod-
ucts, IEC 61010 establishes safety standards for
various electrical environments, categorized as
CAT I to CAT IV, and called measurement catego-
ries. These are defined as follows.
Higher-numbered categories correspond to electri-
cal 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 mea-
surement 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 Stan-
dards.
CAT I Secondary electrical circuits connected to an AC electri-
cal 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 in-
stallations) 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 protec-
tion device (distribution panel).

Follow these precautions to ensure safe operation
and to obtain the full benefits of the various func-
tions.
Usage Notes
Do not attempt to measure the temperature
of objects carrying a voltage. Doing so will
result in a short-circuit accident or an electro-
cution accident.
• This product should be installed and operated
indoors only, between 0 and 40°C and 80% RH.
• To avoid damaging the product, never connect
any sensor other than the 9478 or 9479
SHEATH TYPE TEMPERATURE PROBE to the
sensor connector. Never attempt to input a sig-
nal through the sensor connector. For informa-
tion on the temperature range of use for
temperature probes, see 4.2 "9478 SHEATH
TYPE TEMPERATURE PROBE" (53 page) and
4.3 "9479 SHEATH TYPE TEMPERATURE
PROBE" (54 page).
• Do not store or use the product where it could
be exposed to direct sunlight, high temperature
or humidity, or condensation. Under such condi-
tions, the product may be damaged and insula-
tion may deteriorate so that it no longer meets
specifications.
• Do not use the product where it may be exposed
to corrosive or combustible gases. The product
may be damaged.
• Avoid using the product for long periods if the
unit is soiled with oil or dirt. Doing so may cause
the unit’s case to become warped or damage
the product.

*IP67:
This indicates the degree of protection provided by
the enclosure of the device against use in hazard-
ous locations, entry of solid foreign objects, and
the ingress of water.
6: Protected against access to hazardous parts
with wire measuring 1.0 mm in diameter. Dust-
proof type (Dust shall not penetrate the enclo-
sure.)
7: Watertight (Quantities of water that may harm
the enclosure when it is temporarily immersed in
water shall not penetrate the enclosure.)
• 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 careful not to subject the sheath to
excess stress. Inhaling large quantities of mag-
nesium oxide may be hazardous to your health.
• This product has a dust and water-resistant
construction. However, it cannot be used in
water.
• The protection rating for the enclosure of this
device (based on EN60529) is *IP67.

1.1 Product Overview
The 3447-01 TEMPERATURE HiTESTER is a
water-resistant thermometer designed for use with
the platinum resistance thermometer sonsor
(Pt100).
By using the product in combination with the spe-
cial 9478 SHEATH TYPE TEMPERATURE
PROBE or 9479 SHEATH TYPE TEMPERATURE
PROBE, the product is capable of temperature
measurement within the range -100°C to 300.0 °C.
Equipped with a clock function, the product allows
you to check the time.
This product is ideal for controlling temperatures
since it allows you to record both measurement
temperatures and measurement times at the touch
of a button. (Manual Recording Mode)
Further, the product can be used as a logger for
continuous data recording at a specified recording
interval. (Interval Recording Mode)
This product can store up to 7,200 data items (in
manual recording mode), or 28,800 data items (in
interval recording mode) in its internal memory.
Because data is stored in the unit’s non-volatile
memory, data is not lost when battery power runs
low or during battery replacement.
When the product is connected to a PC via the
optional 9674 RS-232C PACKAGE, you can set
items (product names) and IDs (worker names)
from your computer, and record this information
together with temperature data.
You can also transfer recorded data to your com-
puter and display it.
