Device alerts come in two severities:
• Warnings are less serious and may not require any action to be taken.
• Errors typically prevent normal measurement and require user intervention to recover
from.
Contact Vaisala for support if you are unable to resolve a device alert yourself. From the
Service page of the user interface you can create a diagnostic data file that can help Vaisala
diagnose the device alert. It is recommended that you do this if your DGA monitor stops due
to an error, regardless of if the error was successfully resolved.
Table 13 Device alerts
Code Alert text Severity Description
1098 Measurement cycle started after an
error

started after an error. It is yet
unclear if the error has been
resolved and the measurement

1401 Unable to measure due to unstable
temperature

cycle have been rejected due to

DGA monitor.
2. Wait for the next measurement
cycle to complete to see if the
problem has been solved.
3. Contact Vaisala support is the
problem remains.
1402 Unable to measure due to unstable
light intensity level

cycle have been rejected due to
unstable intensity level of the
