This is a non-contact infrared thermometer used to measure surface temperatures of objects.
USE:
Simply aim the thermometer at the target
with the probe and press the meas. Button
to display the surface temperature.
The distance to target diameter ratio
(Distance:Spot) is 1:1 therefore the device
should be positioned as close to the target
as possible. For example: at one inch, you
will measure a 1 inch diameter area, from
2 inches = a 2 inch area…. and so forth.
