PROBLEM TO BE SOLVED: To diagnose waveform observation, etc., even without preparing any particular device such as oscilloscope. SOLUTION: A device concerned is normally operated from an operation part 1, and its operational guide and results are given on a display 3. At diagnosis of the device, a signal converter 30 takes in a drive signal waveform, etc., of a drive part 18 and digitizes it to be accommodated in a memory 12. Then the signals accommodated in the memory 12 are turned into image data to represent the original drive signal waveform. and the data is sent to the display part 3. That is, the display part 3 for use in the intended service of device proper is allowed to function as a display of a measuring device for displaying the internal signal waveform when the operating mode is the diagnostic. |
