Abstract
A method of calibrating a radiation thermometer including a radiation sensor and an ambient temperature sensor, the method including the steps of using a first radiation standard having a known temperature T.sub.S (1) and with the ambient temperature sensor at a first ambient temperature T.sub.U (1), using the radiation thermometer to read the temperature of the first radiation standard and while doing so, measuring a first output signal U(1) of the radiation sensor; using a second radiation standard having a known temperature T.sub.S (2) and with the ambient temperature sensor again at the first ambient temperature T.sub.U (1), using the radiation thermometer to read the temperature of the second radiation standard and while doing so, measuring a second output signal U(2) of the radiation sensor; and calibrating the radiation sensor and the ambient temperature sensor by using the values obtained for U(1) and U(2) and without using a value for T.sub.U (1) that is derived from measuring an output of the ambient sensor.
