5 Product description 5.1 Design and function CUV5 and SUV radiometers are designed and calibrated to measure global ultraviolet (UV) solar irradiance. There are models for the specific UV bands and they provide measurements in units of W/m2: – CUV5 and SUV5 cover the total UV range. – SUV-A covers the UVA band. – SUV-B covers the UVB band. – SUV-E measures with the standard "Erythemal" response of human skin. The CUV5 radiometer has a low-level analog output signal directly from the detector. SUV radiometers feature internal digital signal processing and outputs for industrial data acquistion...

► Carefully remove the product from the packaging. ► Check that the delivery is complete and undamaged. ► If you find any damage or if the delivery is incomplete, then immediately contact the supplier and manufacturer. ► Keep the original packaging for any further transportation. ► Store within specified temperature ranges. ► Store in original box where possible.

► Check the desiccant of the CUV5 radiometer and replace the desiccant if necessary. ► If using the digital output of the SUV radiometer, set the Modbus® address before visiting the site. Otherwise a computer and RS-485 / USB converter is required during installation. The following tools and aids are required: There should be no obstructions to the field of vision above the instrument's sensor element. If this is not possible, the location of the instrument must be chosen to ensure that obstacles do not rise by more than 5 degrees above the azimuth range between sunrise after the shortest night...

2x flat washers 2x nuts 2 2x nylon insulating rings ► To insulate the instrument against the temperature of the mounting device, place the instrument on the adjustable foot and the two leveling feet. ► Position the instrument in such a way that the nuts are located at a distance of 2 to 3 mm from the mounting device. ► Ensure that the instrument is grounded. ► Ensure that the instrument is not in the shade. ► When installed horizontally, point the cable connector towards the nearest pole to reduce the UV exposure on the cable. ► In order to align the instrument horizontally, rotate the leveling...

Damage due to power supply! The instrument does not require power. Connecting power causes damage to the instrument. ► Do not connect the instrument to power supply. The CUV5 radiometer has a 2-wire cable and 2-pin connector. The maximum recommended cable length is 100 m of good quality shielded 2-core signal cable. Damage due to power or ground loops! Connecting the RS-485 to a grounded circuit and the analog output to a floating circuit can cause ground loops. This may cause differential voltages that will damage the instrument. ► Use either the analog or the digital output. ► Observe the maximum...
