User Manual
The MCA’s infrared sensor uses a small opening. Dirt,
grease, or oil may enter the opening and cause
inaccurate temperature measurements. If necessary,
clean the opening using alcohol and Q-tips.
Environmental Conditions
Watch for environmental conditions in the working
area. Steam, dust, smoke, etc. can prevent accurate
measurement by obstructing the MCA’s optics.
Ambient Temperatures (the surrounding
temperature)
If the MCA is exposed to abrupt ambient temperature
differences of 11
°
C or more (20
°
F), allow it to adjust
to the new ambient temperature for at least 20
minutes before performing temperature
measurements.
Emissivity
Emissivity is the measure of an object's ability to emit
infrared energy. Emitted energy indicates the
temperature of the object. Emissivity can have a
value from 0 (shiny mirror) to 1.0 (blackbody). Most
organic, painted, or oxidized surfaces have emissivity
values close to 0.95. The MCA’s emissivity is set to
0.95 to address most surfaces.
