Measurement valid:
Indicates a valid measurement.
Measurement not valid: Indicates a maintenance condition (details see M_MAINTENANCE)
Busy:
A measurement is actually running.
Failure present:
No new measurement can be started (details see M_FAILURE)
Temporary not ready: No measurement can be started due to internal actions
(usually during upwards movement of the sensor weight).
