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
