Abstract:
1. A method for calibrating a temperature probe for a thermometry apparatus, said method comprising the steps of: characterizing the transient heat rise behavior of a temperature probe used with said apparatus; comparing the characterized transient heat behavior of a said temperature probe to that of a nominal temperature probe and normalizing said characterized transient heat rise behavior based on said comparing step; storing the normalized transient heat rise behavior on an EEPROM associated with said probe; and applying the stored normalized transient heat rise behavior to an algorithm for predicting a final steady state temperature for said probe wherein said characterizing step includes the steps of applying a voltage pulse to said probe and plotting temperature rise versus time and in which said comparing and normalizing step includes the step of comparing the plotted temperature rise curve of said probe to a temperature rise curve for a nominal probe at specified time intervals to determine normalizing coefficients for storing in said EEPROM for applying to said predict algorithm.
