3.5 Fault Condition Warning
The unit can warn the user of an internal fault, i.e. a source failure or
blockage in the Infrared path. When a fault occurs, both LEDs will illu-
minate and the alarm will sound continuously. The following screen will
display until the unit is switched off.
FAULT
If the fault condition warning is activated at any time, then the unit
must be returned to Bacharach for service.
3.6 Data Logging
When the CO
2
Monitor is switched on, it will automatically begin storing
time, date and CO
2
levels at 30 second intervals. Optional BACH-COM
Software allows this interval to be changed (Section 4.1).
Readings are stored with their real time to the nearest second. There is
storage capacity for more than 1,500 sets of readings. Once the storage
capacity has been exceeded, the latest readings will overwrite the oldest
stored data - i.e. first in, first out.
NOTE:
Optional BACH-COM Software is available to pro-
duce tables and plots of real time CO
2
exposure (See Section
4.1 for part numbers).
