Abstract

PURPOSE: To improve the accuracy of calibration without reguiring labor and time by a detector which generates analog electric signals in correspondence to the change in various physical quantities and a detection circuit which has an amplifier outputting the signals from the detector after range-changing the same.
CONSTITUTION: The signals generating from a detector 1 or equivalent signals are inputted to an amplifier 12 and the magnitudes thereof are regulated for each of terminals 16 thru 19 via range changeover switch S2, and are then inputted to an amplifier 20, where they undergo sensitivity adjustment and are outputted. Namely, the range changeover terminals 16 thru 19 are equal to the number of equivalent signal generating circuits and are set and installed in correspondence to their range changeover capacities. For example, the terminals 16, 17, 19, 19 are installed for respective range changeovers of X10, X5, X2, X1 respectively. In this way, the outputs of the amplifier 20, etc. are inputted to an indicating meter such as load gauge or other and the detection physical quantities are displayed in full scale for each range
