2 OPERATOR MODE
2.1 Introduction
Operator Mode (Level 1) is the normal day-to-day mode of the DATUM L160.
Frames displayed in Level 1 are determined and limited by the indicator functions
which are selected during configuration of the instrument – see Section 4.
Note. Only the operating frames relevant to the configured functions are
displayed in Operator Mode.
The three indicator functions are:
• Standard Level Indicator – page 8
• Level Indicator with Max./Min./Average – page 9
• Level Indicator with Volume Indication – page 11
