Thermo Scientific
Auto-Start Function
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 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 workspace is supplied with
the preset quantity of CO
2
.
Note

Ventilate the inner chamber after changing the O
2
setpoint so that no alarm occurs.
Note
Factory settings:

Depending on the type of the O
2
sensor, one of the two O
2
control ranges has been preset at the
factory:

Control range I: 1 % to 21 %

Control range II: 5 % to 90 %
Usage of the process gases:
For set values below 21 % O
2
, the device must be connected to a nitrogen supply system.

For set values above 21 % O
2
, the device must be connected to an oxygen supply system.

For set values of 21 % O
2
, the O
2
control is switched off and error monitoring is disabled as well.
Note
Please make sure that the sensor has been correctly plugged into the socket. Improper installation of
the sensor may cause corrosion at the contacts and calibration errors during the auto-start routine.
You can verify the proper function by simply activating the sensor. When no error message occurs
within 10 minutes, the unit is ready for the auto-start routine.
