6. Handling and control
6.10 Activating the auto-start routine
The auto-start function is an automated routine for the start and the subsequent
adjustment of the CO
2
measuring system. After the start, the device control adjusts
the temperature to the set nominal value while humidity is generated. When tem-
perature and relative humidity have reached constant values, the CO
2
measuring
system is automatically adjusted to these values, and the work space is supp-
lied with the preset quantity of CO
2
.
NOTE – Application of the routine
To ensure that the specified accuracy of the
CO
2
measuring system is maintained, the de-
vice should always be started using the auto-
start routine after the nominal temperature
setting has been changed by more than 1° C
or after extended interruptions of the operation
of the device. The auto-start routine should be
run at least every three months on the occa-
sion of cleaning and maintenance works.
Running the routine usually takes 5 to 7 hours.
At low room temperatures and when the device
is cold, it may take up to 10 hours until the
auto-start routine has been completed. If the
glass door is opened or if the power supply of
the device is interrupted while the routine is
running, the routine is interrupted and rerun
after the glass door has been closed and after
the power supply has been reestablished.
At the start of the auto-start routine, the work
space atmosphere must consist only of ambi-
ent air. The floorpan must be filled with a suf-
ficient quantity of water!
