7.2 Front Panel Menu
This section gives an overview of the front panel menus. The menus are designed to automatically
guide you through all parameters required to configure a particular function or operation. Please
mind that the instrument may work in three different operation modes. They are:
Normal Mode
Safe mode
Multi Gas Mode (MGM)
The manual usually describes the reactions of the instrument in the normal mode. The safe mode
demands for any action the operator intends to do the entry of the operator’s code. The default op-
erator’s code is “111.000” The MGM provides a list of up to 16 binary gas mixtures to be measured
sequentially. It is described separately at the points where it is of interest.
