10.2.1 Stabilization and Accuracy
The stabilization time of the calibrator depends on the conditions and
temperatures involved. Typically the test well is stable to 0.5°C within 20 minutes
of reaching the set-point temperature as indicated by the display. Ultimate
stability is achieved 10 to 20 minutes after reaching the set temperature.
Inserting a cold probe into a well requires another period of stabilizing depending
on the magnitude of the disturbance and the required accuracy. For example,
inserting a .25 inch diameter room temperature probe into a sleeve at 1200°C
takes 10 minutes to be within 0.5°C of its settled point and takes 15 minutes to
achieve maximum stability.
Speeding up the calibration process can be accomplished by knowing how soon
to make the measurement. It is recommended that typical measurements be
made at the desired temperatures with the desired test probes to establish these
times.
