7.2 Electrical installation 7.2.1 Electrical connections of CUV5 radiometer NOTICE Damage due to power supply! The instrument does not require power. Connecting power causes damage to the instrument. 4 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. -
Page 17: Grounding Radiometer
7.2.2.3 Connecting to computer NOTICE Damage due to lack of insulation! The power supply units of portable computers such as laptops can generate large voltage peaks. This may cause damage to the instrument’s digital interface. 4 Ensure that the converter has galvanic separation between the inputs and outputs. The instrument must be connected to a computer via an RS-485 converter with a USB port. -
Page 18: Analog Voltage Output
7.2.4 Analog voltage output CUV5 radiometer The analog voltage output is generated directly by the photodiode detector in response to received radiation. The individual sensitivity is used to convert the output signal in in μV to W/m of irradiance when recorded by a data logger. -

Page 33: Appendix
15 Appendix 15.1 UV broadband radiometers CUV5 and SUV radiometers are designed for continuous outdoor use in routine monitoring applications with the sun as the source. However, they can also be used in indoors in test chambers and laboratories; bearing in mind the specifications of the UV source (lamp) and of the radiometer used. - Page 34 However, when the received solar spectrum changes due to atmospheric conditions, or when a different light source such as a lamp is used, the ratio between the instrument’s enclosed irradiance and the ideal enclosed irradiance can vary and "spectral errors" will occur. The figure below shows the ideal spectral response for "total UV"...
- Page 35 The next figure shows the "enclosed radiation”. This is per wavelength the product of the instrument’s response and the irradiance level at that wavelength. The instrument’s detector signal represents the enclosed radiation; the sum over the whole range of wavelengths, represented by the area under the curve (the integral). Enclosed irradiance for ideal response and CUV5 response Wavelength [nm] The enclosed radiation of the G 173 spectrum as measured by the CUV/SUV5 (light gray solid line)

Page 36: Indoor Measurement With Lamps
Typical spectral errors that can occur for solar irradiance measurement due to spectral changes over solar zenith angles 0° – 70° and total ozone columns 260 – 400 DU are shown in the following table: CUV5 and SUV5 SUV-A SUV-B SUV-E +2 % +2 % +5 % +2 % -2 % -2 % -15 %... - Page 37 To ensure the response at 90° angle of incidence is zero (cos. 90° = 0) a rim shades the diffuser side at SZA >85°. The shape of the diffuser ensures a good cosine response. Due to tolerances of the components and in assembly, there is a slight variation in directional response between radiometers.
