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

4 CONFIGURATION MODE
4.1 Introduction – Fig. 4.1
The Configuration Mode comprises two levels (3 and 4) as shown in Fig. 4.1.
Level 3 is divided into four frames. For most simple applications it is only necessary to
set up the parameters in the first frame.
Note.
When in the Configuration Level:
• All the LED indicators flash.
• All relays and logic outputs are turned off.
• The analog output reverts to 0% (4mA) output level.
