METHOD FOR AUTOMATICALLY CONTROLLING GAIN AND DEFLECTION OF ANALOG DETECTING VALUE

摘要

PURPOSE: A method for automatically controlling gain and deflection of an analog detecting value is provided to display the gain and deflection of the analog detecting value as an approximate value when displaying the analog detecting value in a digital manner. CONSTITUTION: A trimming mode is firstly determined(S100). Based on the trimming mode, a temperature difference between a previous temperature value before the trimming state and a present temperature value is determined(S200). According to the temperature difference, a trimming switch of a temperature sensor section is operated(S300). Then, a difference between a reference voltage value and an analog/digital value is calculated. Gain and offset are adjusted according to the difference between the reference voltage value and the analog/digital value(S400). After that, a present temperature value is stored(S500).
