Abstract

PURPOSE:To facilitate the constant correction of temperature compensation by providing a rotary switch and varying a temperature compensation constant obtained from a read-only memory with the rotary switch. CONSTITUTION:The contact position of the rotary switch 50 is converted into a corresponding code signal, which is supplied to an arithmetic unit 30, so that the primary temperature coefficient of the zero point of the ROM 40 where a temperature compensation coefficient table is written with the code signal. The arithmetic unit 30 processes pieces of information from a pressure transducer 11 and a temperature transducer 21 and the measured pressure in the ROM 40 after temperature compensation, and display the value. This constitution performs the constant correction of the temperature compensation without rewriting the contents of the ROM 40.
