の合否判定装置。[Claims for Utility Model Registration] (1) A comparison circuit compares the resistance value of the reference sensor and the resistance value of the sensor to be measured, and the comparison output operates a pass/fail display circuit to compare the resistance value of the sensor to be measured. A sensor for determining pass/fail, characterized in that a switch is inserted into the power supply line to the comparison circuit and the pass/fail display circuit, and a timer circuit is provided for turning on the switch for a set time. Pass/fail judgment device. (2) The pass/fail display circuit is an LE to indicate pass.
A sensor pass/fail determination device according to claim 1 of the utility model registration claim, comprising: D and a buzzer for notifying failure. (3) The switch inserted into the power supply line consists of a relay circuit, and the timer circuit includes a timer IC equipped with a counter, an RC oscillator circuit coupled to this timer IC, and a reset circuit for resetting the timer IC. 3. A sensor pass/fail determining device according to claim 1 or 2, which comprises a reset switch for operating the relay circuit for a set time from when the reset switch is activated.
