Sensor:
The sensor consists of a GaAsP photodiode and a UV filter. It is completely insensitive to visible light longer than 400 nm and infrared radiation, as its spectral sensitivity only covers the UVA range from 320 to 400 nm. Operation of the device:
To operate your Solarmeter®, aim the sensor window on top of the device directly at a UV source.
Press and hold the pressure switch on the front of the device. For optimal results, note the distance of the measurement from the UV 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®:
• To measure the UV transparency of windows at home, in the business, at school, or in the car, measure through the window or film and compare the values with those outdoors.
• When measuring household lighting, measure near the lamps and increase the distance until the value falls below 1 W/cm².
• When measuring lighting in sports halls or stadiums, measure the values at floor level. Request the installation of UV protection if the readings are too high.
Care and maintenance:
• Avoid exposing the device to extreme temperatures, humidity, 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 device. Keep the sensor free from oil, dirt, etc.
