Abstract:
1. A method of calibrating a temperature display device, comprising the steps of: placing un-calibrated temperature sensor into a controlled environment; placing calibrated temperature display device into said controlled environment; bringing said controlled environment to a first predetermined temperature; reading first data point of said un-calibrated temperature sensor; reading first data point of said calibrated temperature display device; comparing said first data point of the un-calibrated temperature sensor to said first data point of the calibrated temperature display device to obtain a temperature sensor offset value; adjusting the controlled environment to a second predetermined temperature; reading second data point of said un-calibrated temperature sensor; reading second data point of said calibrated temperature display device; and determining actual temperature reading, wherein the determining step further comprises calculating a slope of a line and calculating actual temperature based on said slope and said offset value and herein the slope is determined by the ratio of the difference between the second data point and the first data point of the calibrated temperature display device and the difference between the second data point and the first data point of the un-calibrated temperature sensor.
