ThermoWorks 9141 HART SCIENTIFIC FIELD DRY-WELL TEMPERATURE CALIBRATORS - Manual (Page 42)

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.
