Sealey TA304 - Manual (Page 6)

Note: Infrared measurement considerations.
Holding the laser unit in your hand, direct the laser/Ir sensor toward the
object whose temperature is to be measured bearing in mind the field of
view requirements shown in fig.12. the meter automatically
compensates for temperature deviations due to the ambient
temperature. If a higher temperature is to be measured after taking a
low temperature measurement, it is advisable to wait several minutes
between the measurements for the infrared sensor to cool. Keep in mind
that it may take up to 30 minutes to adjust to wide ambient temperature
differences.
