3.6 Measurement considerations
Hold the meter by its handle, point the IR sensor towards the object whose
temperature is to be measured. The meter automatically compensates for
temperature deviations from ambient temperature.
Keep in mind that it will take up to 30 minutes to adjust if wide ambient
temperatures have been measured. After measuring low temperatures and
before measuring high temperature, allow some time (at least several
minutes) for the cooling process of the IR sensor.
