3.2.2. Warm Up

The M300E requires about 30 minutes for all internal components to come up to
temperature before reliable CO measurements can be taken.

3.2.3. Warning Messages

Because internal temperatures and other conditions may be outside be specified
limits during the analyzers warm-up period, the software will suppress most
warning conditions for 30 minutes after power up.
If warning messages persist after the 30 minutes warm up period is over,
investigate their cause using the troubleshooting guidelines in Section 11 of this
manual. The following table includes a brief description of the various warning
