maintenance demanded.
The measured value is still
output.
0 1 1 1 1 0 0 0 120 0x78 The module is in the "Warming-up" state. The
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.

0 0 0 0 0 0 0 0 0 0x00 The measured value is invalid because it is not
available with the existing device configuration.
The substitute value 0.0 is
output instead of the meas-
ured value.
0 0 1 1 1 1 0 0 60 0x3c The measured value is invalid for one of the follow-
ing reasons:
• A calibration or an AutoCal is being carried out
• Parameters are being downloaded
The measured value is still
output.
0 0 1 1 1 1 1 1 63 0x3f The measured value is invalid for one of the follow-
ing reasons:
• Firmware is being downloaded
• The device is in the pause or standby state
A substitute value or the
last valid measured value is
output instead of the meas-
ured value.
0 0 1 0 0 1 0 0 36 0x24 The measured value is invalid because of a fault or
a maintenance alarm.
The measured value is still
output.

output instead of the meas-
ured value.
0 0 1 0 1 0 0 0 40 0x28 The measured value is invalid because of a fault
