Notes on Use
――――――――――――――――――――――――
DANGER
･Operation of this unit according to any
procedure not specified in this manual may
cause explosion due to dangerous laser
radiation.
･The 3443-01 (field type unit) uses as a light
source a semiconducting laser which emits
visible light, and which conforms to JIS
standard class 2 (JIS C6802). (Wavelength
670nm, maximum power output 1 mW)
Since there is considerable danger of this laser
light causing damage to the eyes, be very
careful not to direct this laser light into your
eyes or those of another person.
･Do not look directly into the laser light from the
optical system.
･When measuring the temperature of an object
which has a mirror finish, be careful not to allow
the laser light beam to be reflected off the
surface into your eyes or those of another
person.
･Do not allow the laser light beam to impinge
upon any gas which can explode.
Notes on Use
In order to ensure safe operation and to obtain
maximum performance from the unit, observe the
cautions listed below.

WARNING
･To prevent electric shock, do not allow the unit
to become wet and do not use the unit when
your hands are wet.
･Ensure that protective functions are fail-safe:
that is to say, that if they fail they either prevent
the unit from operating or give an indication to
prevent unwitting operation.
CAUTION
･Do not use the unit near any device which
generates strong electromagnetic radiation or near
a static electrical charge, as these may cause
errors.
･The unit should always be operated indoors in a
range from 32 to 104 (0℃to 40℃) and 35% to
85% RH or less. Do not use the unit in direct
sunlight, dusty conditions, or in the presence of
corrosive gases.
･Do not store or use the unit where it will be
exposed to direct sunlight, high temperatures, high
humidity, or condensation. If exposed to such
conditions, the unit may be damaged, the insulation
may deteriorate, and the unit may no longer satisfy
its specifications.
