する指針型メータの調整検査装置。 A test signal generator that outputs a test signal for driving the needle to the meter, a television camera that photographs the display section of the meter, an XY movement mechanism in which one of the television camera and the meter is installed, and a rotating section for adjusting the meter indication. A rotating mechanism to which is coupled, an image processing means that image-processes the output signal of the television camera and detects the meter needle and scale, and movement commands and test signals for the XY movement mechanism necessary for the image processing means to detect the scale. Commanding the output signal value to the generator, calculating the indication error between the meter scale and the needle, comparing the tolerance value given by the length in the circumferential direction with respect to the meter scale, the indication error and the tolerance range, A pointer-type meter characterized by comprising a rotation command to a rotation mechanism to bring the indication error within an allowable range, arithmetic control means for measuring the operating time of the meter needle, and comparing the operating time with a specified value. Adjustment inspection device.
