6.1 Precautions in installation
This product IR-
CZQH7□ is a precision instrument. Please install it on the occasion of setting with care
to the following item.
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 or power line.
Working temperature
The working temperature of the thermometer is -10 to 60ºC. 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.
