timate stability will be achieved 10 to 20 minutes after reaching the set

temperature.

Inserting a cold probe into a well will require another period of stabilizing de

pending on the magnitude of the disturbance and the required accuracy. For ex

ample, inserting a .25 inch diameter room temperature probe into a sleeve at

300°C will take 5 minutes to be within 0.1°C of its settled point and will take

10 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.
