INSPECT TELEVISION CAMERA ASSY:

Standard signal check
1. Using the tester, measure the voltage and the continuity between terminals.
  HINT:
  
  Leave the connector being connected.
2. Using the oscilloscope, check wave forms between terminals.
  HINT:
  - Leave the connector being connected.
  - The waveform shown is merely an example.
  Noise waveform and chattering waveform are omitted.
  
  Standard:
