Solar Sensor: Testing and Inspection

SOLAR RADIATION SENSOR INSPECTION




1. Shine an incandescent light (approx. 60 W) directly on the solar radiation sensor from approx. 100 mm (3.9 in).
2. Using a tester, connect the positive (+) lead to solar radiation sensor terminal A, the negative (-) lead to terminal B and verify that the output voltage is approx. 0.45 V.
- If the voltage is not normal, replace the solar radiation sensor.
