5.4 Cautions on measurement
Beam attenuation
・Never directly face the objective lens to the sunlight for protecting your eyes
and the detecting element.
・Set the beam attenuation filter selector k
nob to the beam attenuation side in
advance (in case of Model IR-AHS or IR-AHU) for protecting your eyes on
the measurement of object exceeding 1500oC.
・However , when you feel glare on the measurement of objects lower
then 1500 oC, set the beam attenuation filter selection knob to the beam
attenuation side in advance.
・Light path
Be careful not to introduce water drops, dust particles, smoke, steam, or other
foreign substances into the light path between the object measured and the
objective lens of this thermometer.
・Interference causing high indication
Be careful not to apply the direct sunlight, light of an incandescent lamp, flame
or other thermal radiation to the object measured and the objective lens of this
thermometer.
・Abrupt change of ambient temperature
Model IR-AHT uses a thermopile as its detecting element. If the ambient
temperature changes abruptly, it takes time until the indication is stabilized.
If your thermometer is Model IR-AHT and it has been brought into a place
where a temperature difference is noticeable, leave the thermometer for about
one hour before starting the measurement.
