摘要：PURPOSE:To make corresponding the scale easily to the measuring input and specifications, by a unit-sized scale circuit. CONSTITUTION:The input Ei fed from the input terminal 1 is input to the variable resistor Rp of the potentiometer circuit 4 each one side of which is formed with resistors R1, R2, R3 and R4. This resistor Rp is driven with a servo motor M, and the input Ei is indicated with the scale in interlocking with the motor by stopping the motor M when the input Ei and the output Etheta of the circuit 4 are equal. In this case, with the resistance values of R1=R3=0, R3=0 or R1=0, the measuring range is a given positive value from 0, from a given positive value to a further greater positive value, and a value between negative/positive specified values. Thus, the potentiometer circuit 4 is unit-sized, and this is replaced according to the measuring range, allowing the correspondence of scale easily against the change in the input and specifications. Further, when the unit is formed with dual-inline package and the terminals are commonly used, the power is made greater.
