Solar Sensor: Testing and Inspection

SOLAR RADIATION SENSOR INSPECTION

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 infinity 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
- infinity ohms (no continuity)

3. Expose the solar radiation sensor to natural sunlight.






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

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

Resistance
- except infinity ohms
