Caution
Simplified adjustment with the wizard is basically only possible with an
open calibration switch of the ERZ2000-DI.
However, the notice on removal of seals (
chapter 1.5.2 Seal diagram for
devices with MID approval
) must be observed!
If the calibration switch is closed - for legal custody-transfer purposes - almost no
settings are possible on the wizard screens.
Secondly, the user profile must be specified.
"User"
should be selected for as an
"ordinary" user of the flow computer;
"Service"
can also be selected for internal
settings.
All
settings options that are necessary for parameterization are available to a
"
User
". Then the simplified adjustment of the ERZ2000-DI with the help of the wiz-
ard is also enabled.
Note
Recommendation:
Please choose User as a user profile!
The wizard (and the ERZ2000-DI) displays only the parameters that are rel-
evant according to the intended use for the selected device type. Com-
plete settings menus and/or individual parameters are hidden (in the wiz-
ard and coordinate system of the ERZ2000-DI).
The wizard should be used in the specified sequence. In this case, unnec-
essary additional settings options are hidden on the subsequent pages af-
ter settings have been changed. If, for instance, the GERG 88 S is selected
for state equation of the gas composition, only the relevant input values
for this calculation are required as entries. Portions of gas components
such as methane or other types are no longer displayed or queried.
Scrolling past, forwards or backwards can result in unnecessary entries or
corrections if these settings have not been carried out (yet).
The settings that are initiated with the recommendation button are also
made on the basis of entries which were already made
–
then they are only
permitted/logical if the sequence has been observed.
