TAKING MEASUREMENT SAMPLES
To take temperature measurements,
point the instrument at the surface to
be measured and pull the trigger.
A tube has been incorporated along the
top of the barrel to aid the user in
spotting the surface area to be
measured (target).
Although this simple explanation works
well in most cases, there are other
factors that may impact the
measurement accuracy.
Consider these influences before using
the data you obtain with your infrared
thermometer:
The target must completely fill the
spot diameter seen by the infrared
sensor, otherwise the temperature
displayed will be influenced by the
surface surrounding the target.
The ratio of the distance from the
end of the barrel to the size of the
spot being measured is 12
: 1.
