Page 11: Introduction
1. Introduction The SMP10 pyranometer, manufactured by Kipp & Zonen and cabled by Campbell Scientific, measures solar radiation with a high-quality blackened thermopile protected by two glass domes. Its flat spectral sensitivity makes it ideal for applications in natural sunlight, under plant canopies, and in greenhouses or buildings. -

Alternatively, remove the sensor levelling feet to allow it to be mounted directly to the mounting bracket. 2. Secure the solar radiation sensor to the mounting bracket. The blue dots in the following figure indicate the mounting holes used for this pyranometer. SMP10 Pyranometer... - Page 13 For pyranometers mounted horizontally, ensure the mounting bracket is horizontal in two dimensions. For pyranometers mounted at an angle, set the mounting bracket angle to the desired angle prior to tightening the mounting hardware. SMP10 Pyranometer...

7. RS-485 programming The RS-485 output can be directly read by a MeteoPV, CR6-series, CR1000X-series, or Modbus RTU RS-485 network. Other Campbell Scientific data loggers can use an MD485 multidrop interface to read the RS-485 output (refer to the MD485 manual). -

Page 20: Maintenance And Troubleshooting
10. Maintenance and troubleshooting The SMP10 has no service items requiring scheduled replacement. There is no accessible desiccant cartridge to maintain. Use pure alcohol or distilled water and a lint-free cloth to clean the dome, removing smears and deposits. Local conditions and application dictate cleaning interval. - Page 22 Global Sales & Support Network A worldwide network of companies to help meet your needs CANADA GERMANY FRANCE CHINA SPAIN SOUTHEAST ASIA COSTA RICA Campbell Scientific group companies Sales representatives AUSTRALIA BRAZIL SOUTH AFRICA Australia Costa Rica Southeast Asia Garbutt, QLD Australia...
