Total reset
With a total reset, all adjustments which can
be carried out via VVO or MINICOM are
reset.
This includes, e.g., the following data:
- electrode type
- Tag name
- offset correction
A total reset is necessary, e.g. if the oscilla-
tors are installed on another electrode.
Setup
Under the menu item "Configuration", you can
choose the following functions:
• Measuring system
• Measurement loop
•Program
The electrode is already preset at VEGA. The
measuring system must only be configured if
the oscillator is exchanged.
Measuring system
In this window, you can choose the respec-
tive electrode. You can find the electrode
type on the type plate of the instrument.
Choose the correct electrode from the list,
e.g. EL 21: 14 mm PTFE. In front of the listed
electrodes you see the electrode type
number. The number belonging to your ca-
pacitive electrode is stated on the type plate
(see also chapter "1.6 Type plate"). If your
electrode is not included in the list, choose
´not configured´ . Push the Save button to
confirm the setting.
Information on the sensor ident number:
You do not have to modify the setting "VEGA
specific No.". Only if you want to make sure
the sensor can be replaced on the Profibus
by a sensor from another manufacturer do
you have to choose the option "Profile spe-
cific No.".
