Abstract

PURPOSE: To achieve feasibility of the use of ordinary reed relays and the feasibility of adaptation to high speed testers by using a window type comparator, preset type up-down counter, etc.
CONSTITUTION: A window type comparator 23 and a preset type up-down counter 24 are connected to an amplifier 8 connected to an analog input signal source 7, by way of comparators 21, 22 etc. Then, an oscillator 26 is turned ON and OFF by the control signal from the window type comparator 23. The clock pulse outputs thereof are inputted to the preset type up-down counter 24 and are thereby counted. The output thereof is then inputted to a decoder circuit 29, by whose output range changeover relays 30 thru 31 are driven and relay contacts 12 thru 14 are subsequently changed over. If the one in which two or more sets of relays do not actuate is utilized as the decoder circuit 29 and feedback resistances 9 thru 11 are suitably selected, the transient overshooting at the time of changing over is eliminated.
