7.3.4 Sensors with Rain Gauge
 Installation on the top of the mast or on crossbar with distance to the mast
 Mast or crossbar mounting shall be exactly perpendicular, otherwise the precision of the
rain gauge may be influenced.
Note: The location should be selected so that pollution of the rain gauge funnel by falling
leaves etc. can be avoided as far as possible.
7.3.5 Sensors with Global Radiation Measurement
 Installation on top of the pole
 Shadow free location, if possible 360° free view to the horizon at the height of the
pyranometer
 Distance to shadow casting objects (trees, buildings) at least 10 times of the object height
relative to the sensor.
