3.2 Display and Function
The LCD screen shows all measurement values of the analyzer and all customer
instructions. You can operate with five function keys, four arrow keys (cursors) and the
enter key. The function of each key depends on:
♦ the type of analyzer/analyzer module used
♦ the optional auxiliary modules (e.g. I/O boards) used
♦ the individual menu displayed
In case of power failure all customer specific module parameters are saved by a battery-
powered buffer.
