SGP EBBR E26 - All Data Incorrect
DataStreams:sgp30ebbrE26.b1, sgp15ebbrE26.b1, sgp5ebbrE26.b1, sgp5ebbrE26.00
Description:
All data was incorrect during these periods for unknown reasons.
However, this tends to happen during preventative maintenance
visits if sensors have to be changed out or tested and the 
datalogger program is reloaded, or if the battery voltage is low.
Suggestions:
