Sensor:
GaP photodiode, packaged in a hermetically sealed UV glass window cap. Filter to reduce sensitivity, as shown in the spectral sensitivity chart.
Operation of the device:
To operate your Solarmeter®, align the sensor window on the top of the device directly with a light source. Press and hold the pressure switch on the front of the device. For optimal results, note the distance of the measurement from the source to ensure repeatable results.
The battery operating voltage is adjustable from 9 V down to 6.5 V. Below 6.5 V, the numbers on the LCD display begin to fade, indicating the need for a battery replacement. With typical usage, a standard 9V battery lasts about 2 years.
Correct use of the Solarmeter®:
- Wear eye protection when checking the UV lamps (goggles that offer all-round protection are ideal)
- Allow the lamps to warm up before taking measurements (at least 15 minutes).
- Keep the integrated sensor of the device close to the source to measure the intensity of individual lamps or LEDs. Keep the sensor at the working distance from the source to measure the effective intensity.
- When checking the aging of lamps, keep the measurement distance and locations consistent.
- Lamps should be replaced when their performance drops to about 70% of their original (new) readings.
- If you’re unsure of the new values, replace one lamp with a new one and compare the old readings.
Care and maintenance:
- Do not expose the measuring device to extreme temperatures, moisture, shocks or dust. If the device is accidentally exposed to excessive humidity or wet conditions, unusually high readings may occur. If you allow the device to dry naturally or place it in a bag with silica gel, normal function will be restored.
- Use a very soft cloth to clean the meter. Keep the sensor free from oil, dirt, etc.
