SOLAR RADIATION SENSOR INSPECTION

id074000802900

1. Using a tester, connect the positive (+) lead to solar radiation sensor terminal A, the negative (-) lead to terminal B or C, then measure the resistance.

  • If the resistance is not normal, replace the solar radiation sensor.

  Resistance

  except ∞ ohms

2. Block the light to the solar radiation sensor, connect the positive (+) lead of a tester to solar radiation sensor terminal B or C and negative (-) lead to terminal A, then measure the resistance.

  • If the resistance is not normal, replace the solar radiation sensor.

  Resistance

  ∞ ohms (no continuity)

3. Expose the solar radiation sensor to natural sunlight.
