Data 

Weekly 

Check  the  daytime  irradiance  data  and 

compare  to  previous  days  or  adjacent 

pyranometers     

When large difference occur operating 

problems or installation issues can be 

detected.     

Data 

Weekly 

Check night time irradiance values 

Nighttime  offsets  and  sensor  stability 

issues can be revealed.   

Data 

Weekly 

For  the  S-series  with  Modbus  output 

check the body temperature.   

Temperature  changes  can  cause 

offsets  and  change  of  sensitivity  due 

to 

the 

detector 

Temperature 

dependency.     

Data 

Weekly 

For  the  S-series  with  Modbus  output 

check the relative humidity. 

The condition of the drying agent can 

slightly  change  over  time.  The 

acceptable limits for the RH < 90 %   

Data 

Weekly 

For  the  S-series  with  Modbus  output 

check the tilt position. 

Any  change  in  tilt  position  after  the 

installation 

can 

affect 

the 

measurements  due  to  the  cosine 

response of the sensor.
