4.1 Precautions in Installation
This IR-SA series radiation thermometer is a sensitive instrument.
Install it by referring to the following cautions.
●
Vibration and impacts
Vibration or impacts reduces the liability of the thermometer and causes an
unstable measurement by the targeting shake to a measuring surface.
If you install the thermometer in the place where vibration or impacts exist, its
careful periodic inspection is requested.

●
Induction
The thermometer is designed for anti-induction but install it as far as possible
from an induction heating generator and power line distance factor.

●
Working temperature
The working temperature of the thermometer is 0 to 90ºC. If the ambient
temperature is high, or if the temperature of the thermometer exceeds the
maximum working temperature by reflection from a high temperature
substance, etc., water-cooling of the thermometer is absolutely necessary.
When the temperature of the thermometer does not exceed but closely reaches to
the maximum working temperature, water-cooling of the thermometer is
recommended for maintaining of the reliability of the thermometer.

●
Optical path
Select a place for installation of the thermometer, where water-drops, dust,
smoke, steam, etc. would not enter between the thermometer and a measuring
surface.
If such place cannot be selected and the affection by existence of such substances
cannot be ignored, blowing-out of such substance with air-purge is necessary.

●
Disturbances to make indication of measured value higher
Select a place for installation of the thermometer, where sunlight, light of
incandescent lamp, flame, heat radiation from a high temperature substance,
etc. is not reflected to the measured surface and the cover glass of the
thermometer. When such light is reflected, higher temperature than the exact
one will be indicated. (The affect by such reflection will be great for the
measurement of low temperature.) If such place cannot be selected, shade the
thermometer or take similar precautionary measures.
