PURPOSE:To inspect the measure potential to make fault diagnosis possible, by designating respective output values by a change-over switch to display the output value by an LED in case that the control state of the computer which processes plural signals generated at different timing is diagnosed. CONSTITUTION:The output of potentiometer 67 is converted to a digital value by the A/D converter incorporated in the digital computer, and output values of the A/D converter at different timing are stored in the computer. Respective output values are designated by a changeover switch, and the output value is displayed digitally on a basis of designation by the LED. As a result the measure potential can be inspected easily without external measuring devices for voltage calculation and so on only by switching the switch as a designating means. Further, since potentials generated at different timing can be inspected easily, the fault of the device equipped with the potential detector can be diagnosed. |
