Page 3: Introduction
1. Introduction The SR05, manufactured by Hukseflux Thermal Sensors, is an ISO 9060:2018 spectrally flat Class C (second class) pyranometer designed for general solar radiation measurements in agricultural and meteorological networks and PV monitoring. Both analog output and Modbus over RS-485 are supported. -

Alternatively, remove the sensor leveling 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. SR05 ISO Spectrally Flat Class C (Second Class) Pyranometer with Various Outputs... - Page 5 5. 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.

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 14: Maintenance And Troubleshooting
10. Maintenance and troubleshooting The SR05 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 15 See Product Details on the Ordering Information pages at www.campbellsci.com.
