Out of specification: The measured value is unreliable because an
instrument specification was exceeded (e.g. electronics temperature).
This status message is inactive by default.
Maintenance: Due to external influences, the instrument function
is limited. The measurement is affected, but the measured value is
still valid. Plan in maintenance for the instrument because a failure is
expected in the near future (e.g. due to buildup).
This status message is inactive by default.
