Abstract
A method for automatically measuring the amount of photo-coupling, which comprises the following steps: (1) positioning a photo-coupling element on a jig; (2) using a program stored in a photo detection instrument to detect whether the photo-coupling element is positioned correctly; (3) continuing the detection if it is not being positioned correctly on the jig; if it has been positioned, separately flowing a plurality of sets of current through the light emitting elements of the photo-coupling element, and storing the data of the generated photo-coupling; (4) analyzing for which current is most suitable for the photo coupling element thereby matching it with a control element of an application device; (5) if the optimum data have been obtained, displaying the data with the photo detection instrument; if the optimum data have not been obtained, displaying an information indicating that the quality of the photo-coupling element is not good; (6) resetting it; (7) removing the photo-coupling element; (8) next, returning to the step (1); thereby, detecting the characteristics of a photo-coupling element prior to assembly, and measuring a suitable impedance of the resistance matching the light emitting element, so that the impedance of the resistance can match with the photo-coupling signal generated by the photo-coupling element thereby matching with the control element of the application device.
