INSPECT TELEVISION CAMERA ASSY

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