DESCRIPTION AND FUNCTION OF DIP-SWITCHES

The system allows certain changes of specific parameters:
1. Connection of an optional printer.

2. Change of parameters (temperature and time).

3. Setting autoclave identification, if there is more than one autoclave in

vicinity.

4. Stand by shoot mode.

5. Selecting

between

C, kPa, PSI.

6. Selection of dry cycle shoot mode for the quick or regular autoclave.

Changing the position of the DIP - SWITCH, as described below determines

these parameters.
