30/01/2020 16:27 - 17:11 Four Lane Ends Precision LSO Service

For details See GitHub github.com/urbanobservatory/deployments/blob/master/Precision%20Station%20Reports/FOUR_LANE/LSO_Calibration_Sheet_v1.20_FOUR_LANE_20200130.xlsx

LSO aborted due to high winds.

CO autospan not rising above ambient.

NOx manual span looks flawed (NO2 increasing , not trending to zero during span)

CO zero also looks incorrect.

Likely that a callout is required. 

Repeat LSO CO and NOx span tomorrow
