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.
Proper Use of the Solarmeter®:
• Wear eye protection when checking UV lamps (ideally, wraparound safety glasses).
• Allow lamps to warm up before taking measurements (at least 15 minutes). • When checking lamp aging, use the same location and distance to ensure accurate readings. • Lamps should be replaced when output drops to approximately 70% of their original (new) readings. • For curing lamps, hold the meter at the distance where you intend to cure your workpiece. • To measure the total output in the center of a tanning bed, hold the meter facing upward with the bed lid closed. • To measure individual lamps, hold the meter against the acrylic with the tanning bed lid open. • This meter detects UVA “tanning” rays. For erythemal measurements, use Model 7.0 MED/hr. • For acrylic panel testing, take readings with and without the acrylic at the same distance. • When comparing different lamp types, consider readings as relative rather than absolute. • Lamps peaking near 365 nm (newer models) will show higher readings than those peaking near 350 nm.
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.
