Abstract

PURPOSE: To improve the efficiency of test and inspection, by automatically measurement displaying items required by utilizing the electric output of a potentiometer for detecting the reciprocation of a wiper device.
CONSTITUTION: A wipe angle measuring circuit 10 is subject to voltage signals from an endless potentiometer 1 mounted to a nose of a pivot of a wiper device and difference between the maximum value and the minimum value is used as voltage difference, a being-caught changing angle measuring circuit 20 employs the voltage signals of the potentiometer 1 as signals corresponding to the variation of wiper arm wipe operation through a HPF in 10Hz and difference between the maximum value and the minimum value is used as differential voltage, and a wipe period measuring circuit 30 similarly measures a wipe one period. A measured value display circuit 40 is subject to the output signals of said each circuit and displays the voltage converting value θV and ΔθV of wipe angles and being-caught changing angles and a wipe period t in digital shapes, and an operation display circuit 50 computes t×ΔθV/θV, etc. and displays discriminating value deciding the quality of the wiper device.
