Note
All visual IR thermometers need sufficient warm-up time for the most
accurate temperature measurements. This time can often vary by
model and by environmental conditions. Although most visual IR
thermometers are fully warmed up in 3 to 5 minutes, it is always best
to wait a minimum of 10 minutes if the most accurate temperature
measurement is very important to your application. When you move a
visual IR thermometer between environments with large differences in
ambient temperature, more adjustment time can be required.
