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 temperature and relative humidity have reached
constant values, the CO
2
measuring system is automatically adjusted to these values, and the
work space is supplied 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 device
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 occasion 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 ambient air.
The floorpan must be filled with a sufficient quantity of water!
