47252-EN-210205
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 required:
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.
