Abstract
PURPOSE:To enable the common use of other circuits and to enable the sharp reduction in the number of processes required for manufacturing, by a method wherein a resistance in an input circuit is formed into a unit system according to a manufacturing input signal or a scale specification, and is formed into an interexchangeable type. CONSTITUTION:An input signal ei1 is amplified by means of a feedback resistance R1 of an amplifier A1 to produce a given voltage corresponding to an input span voltage, and is sent to an operational amplifier A2 via a resistance R7. Only in case the input signal is a thermocouple input, a temperature composition voltage ec is applied to the operational amplifier A2 via a resistance R2, and a shift voltage +er or -er is further applied via resistances R3 and R4. The feedback resistance R1 and input resistances R2 and R3, and R4 are constituted as a resistance array housed in a dual line package to be formed into a unit, and is designated to be mounted detachably at a socket or the like on a printed substrate. In case there is an alteration in a scale specification, the exchange of only the required unit is sufficient enough, thereby realizing a low cost and simplicity of the system as well as the easy maintenance thereof.
