Title:
THERMOCOUPLE THERMOMETER
Document Type and Number:
Japanese Patent JP3195640
Kind Code:
B2
Abstract:
PURPOSE: To enable execution of offset addition for shifting a zero-position of a temperature waveform by a simple construction by setting an offset value by an offset setting means.
CONSTITUTION: An analog voltage amplified by an amplifier circuit 11 is converted 12 into digital data. In a linearization table 13, main storage areas storing linerized data corresponding to the kinds K, J and T of thermocouples and subdivided subordinate storage areas are provided. When sensor kind information shows the thermocouple K and range information shows 20°C/DIV (scale), for instance, linearized data in the subordinate storage area for 20°C/DIV belonging to the main storage area for the thermocouple are selected. The data are inputted to an offset table (ROM 2) 16. ROM of a storage capacity 256K is used, for instance, for the table 16, and based on offset information from an offset setting means 17, a zero-position of a temperature waveform on a display screen can be shifted equally with offset addition.
