C 1100 Alarm internal data logger
The display shows the TWA value that
is an average value of the latest 8 hours
of recorded CO
2
levels. The logging is
active in On Mode and resets in Off
Mode (resets only if battery charger is
not connected).
All samples taken during
the eight hours (120 samples) can be
viewed with the User Interface Program
UIP-P. From UIP-P it is also possible to
save all data in a PC text file for storage
or further data processing.

extracted from the C 1100 unit using UIP-P
Selecting “Update” in the UIP-P “CO2 history” map will only display data up to the time
position of the sample counter. Setting C 1100 in Off Mode will reset to zero the sample
counter from the previous session of recorded data. The old data still remains, however, until
new recordings eventually overwrite it. After a power up such “lost” data may be recovered
by selecting “Update” with the
right
mouse button.
