4.3 Targeting
For the accurate temperature measurement, target at an object correctly
The following figures (1), (2), and (3) show the correct targeting based on the relation of the
measuring distance and the measuring diameter.
(1) For the measurement distance is shorter than 3m
Measurement diameter becomes “larger” than the targeting mark.
(2) For the measurement distance is about 3m
The measurement diameter and the inner side of the targeting mark are almost “same”.
(3) For the measurement distance is longer than 3m
Measurement diameter becomes “smaller” than the targeting mark.
4. Preparation for measurement
(1) For the measurement
distance is shorter than 3m
(2) For the measurement
distance is about 3m
(3) For the measurement
distance is longer than 3m
• The measuring diameter is fixed to ø20mm for the measuring distance up to 4m.
• For the measuring distance shorter than 3m, make sure to have the measuring
diameter larger than the targeting mark.
