VEGA VEGASON 64 Foundation Fieldbus - Manual (Page 32)

6.4 Setup procedure
As VEGASON 64 is a distance measuring instrument, the distance
from the sensor to the product surface is measured. To have the real
product level displayed, an allocation of the measured distance to the
percentage height must be made. To carry out this adjustment, the
distance is entered with full and empty vessel. If these values are not
known, an adjustment with the distance values, e.g. 10 % and 90 % is
also possible. Starting point for these distance specifications is always
the lower side of the flange, with all other versions the lower side of the
transducer.
The actual level is then calculated on the basis of these entered
values. At the same time, the operating range of the sensor is limited
from maximum range to the requested range.
The real product level during this adjustment is not important, because
the min./max. adjustment is always carried out without changing the
product level. These settings can be made ahead of time without the
instrument having to be installed.
In the main menu item "Basic adjustment", the individual submenu
items should be selected one after the other and provided with the
correct parameter values.
Start your parameter adjustment with the following menu items of the
basic adjustment:
Proceed as follows:

3 Prepare the % value for editing with [OK] and set the cursor to the
requested position with [->]. Set the requested percentage value
with [+] and save with [OK]. The cursor jumps now to the distance
value.
4 Enter the suitable distance value in m for the empty vessel (e.g.
distance from the sensor to the vessel bottom) corresponding to
the percentage value.
