Note:
For optimum adjustment of the measurement, the individual submenu
items in the main menu item "Setup" should be selected one after
the other and provided with the correct parameters. If possible, go
through the items in the given sequence.
The procedure is described below.
The following submenu points are available:
The submenu points described below.
Adjustment process
A parameter change with SIL qualified instruments must always be
carried out as follows.
•
Release adjustment
•
Change parameter
•
Lock adjustment and verify modified parameters
This ensures that all modified parameters were consciously changed.
Release adjustment
The instrument is shipped in locked condition.
As a protection against unintentional or unauthorized adjustment, the
instrument is locked against all parameter changes in normal operat-
ing condition.
For each parameter change you have to enter the PIN of the instru-
ment. In delivery status, the PIN is "0000".
If adjustment is enabled, the safety function must be considered
as unreliable. This applies until the parameterization is terminated
