3 Terms and meteorological units
3.1 Terms
3.1.1
calibration mode (direct measurement mode)
display mode for measurement or calibration of infrared thermometer, indicating the temperature without any correction, that is, the measurement result of blackbody temperature
3.1.2
estimation mode
display mode for measurement of infrared thermometer, indicating the estimated temperature after correction of factors such as environmental temperature change, emissivity, and body position measured
3.1.3
laboratory error
the difference between the uncorrected temperature measured by the blackbody calibrated infrared thermometer and the blackbody temperature under certain ambient temperature and humidity conditions
