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.
