7.3 Entering a submenu
The main menu consists of five submenus.
Figure 7-4 Main menu
Some of these are protected against unauthorized access by various level codes.
Menu Code level
Analyzer status Not coded
Calibration Code level 1
Measuring ranges Code level 1
Parameters Code level 1
Configuration Code level 2
The code of level 1 is preset to "111" in the factory, and the code of level 2 is preset to "222".
Entering a submenu
If you select a submenu by pressing the associated softkey, the code of the corresponding
operation level is queried once (exception: the submenu "Analyzer status" is freely
accessible; selecting this does not change the operating mode).
Decoding level 2 also decodes level 1.
By entering a corresponding code, the device switches to the operator control mode,
whereby the functional check is activated.
The functional check "CTRL" (shown in the status line of the measured value display) is
always activated by the device when an intervention endangers correct measurement, e.g.
when the code is entered. If you have configured a corresponding relay using function 71
with "Functional check", an extra signal is sent out via the relay contact together with the
decoding. This relay contact then signals every functional check activation, e.g. even the
warm-up phases and calibration states of the device.
Decoding also activates the measured value memory, providing you have parameterized it
using function 77. The coding status of the device can be read in the status line of the
measured value display as a symbol "■ CODE" for "coded" or "□ CODE" for "decoded".
