• The target surface should be as vertical to the optical axis as possible. It is recommended that the
angle of oblique image plane should be less than 45°.
• The target image pixels should be more than 5 × 5.
• If multiple presets will be taken for temperature measurement, it is recommended to set the patrol
time above 20 s.

thermography is not recommended in case of deviation occurring during device movement to affect
temperature measurement accuracy.
