5.10.5 Operation with PC/ laptop (optional)
If equipped with the communication or premium module, the incubator can optionally be
used, controlled and programmed with a PC/laptop. It has corresponding communication
interfaces for this purpose (see page 13 and page 58 ).
Operation is described in a separate manual. It is delivered with the incubator for
the relevant models.
5.11 During operation
Regularly check the water level. If necessary, add distilled water.
Warning messages during operation: See Page 40 .
CO
2
mode
In the heating up phase, the CO
2
controller is initially deactivated. The CO
2
intake is inter-
rupted during this period. About 5 minutes after the setpoint temperature has been reached,
the CO
2
control begins measuring and CO
2
gas is let in to the chamber via a sterile filter (the
valve on the gas bottle must be open). To ensure a homogenous distribution of the CO
2
gas in
the interior, the gas is piped in above the chamber fan. The setpoint can be adjusted in 0.1 %
steps from 0 to 10% (for models with CO
2
or premium modules 0 to 20 %)
After a sterilisation procedure, and in cycles every 24 hours, an automatic zero balance
adjustment is carried out. This automatic zero balance adjustment is completed after a
few minutes.
Displays in CO
2
mode:
H E A T U P
HEAT UP is shown during the heating up phase of
the CO

sensor. In the CO
2
display, CO

AUTOZERO - DO NOT OPEN DOOR is displayed during the
zero balance adjustment.
