7 Calibration of Radiation Thermometers
7.1 Preparation
The furnace control setting will usually be the normal working temperature of
the thermometer to be tested. The target temperature is either that indicated
by the measuring thermocouple displayed on the controller indicator, or that
indicated by a standard radiation thermometer.
7.2 Thermometer calibration
When the source is stable at the chosen control temperature, place the
thermometer under test in the holder and measure the thermometer output.
Note the target temperature immediately.
7.3 Calibration procedures
When calibrating radiation thermometers it is important to follow documented
step-by-step procedures to ensure that specied calibration conditions are met,
irrespective of operator. If difculty is experienced in writing procedures, LAND
Instruments International will be pleased to offer guidance.
