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.
3.3 "TAG" and Operating Keys
At the top left of each menu page you will find the tag of the current channel.
Typical tags:
♦MLT/CH1/R1: MLT Analyzer or Analyzer Module / CHannel 1 / Range 1
♦
In this manual you will find normally "TAG" as general name. But in the specific MLT menu pages you will find "MLT".
