maintenance demanded.
The measured value is still
output.

measured value is uncertain because the ambient
conditions are outside the specifications.
The measured value is still
output.
0 1 0 0 1 1 1 1 79 0x4f The measured value is not available because the
device is in the initialization phase (startup) or
measuring mode has not yet been started.
An initial value is output
instead of the measured
value.

output instead of the meas-
ured value.

output instead of the meas-
ured value.
