VEGACAL 62 measures the capacitance of the respective product. To
display the actual level of the product, an allocation of the measured
capacitance to the percentage height must be carried out. For this
adjustment, the capacitance is entered with emptied and filled vessel.
If the vessel cannot be emptied or filled completely, you can carry out
the adjustment also with two known levels - for example with 10 %
and 90 %. The difference between the empty and full adjustment
values should be as large as possible.
The actual level can then be calculated on the basis of these settings.
VEGACAL 62 must be installed. A change of level is necessary for
this adjustment.
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.
Tip:
If the display and adjustment module remains on the probe as a
display, we recommend saving the sensor data in the display and
adjustment module.
Use the function "Copy sensor data".
Start your parameter adjustment with the following menu items of the
basic adjustment:
To be on the safe side, note the adjustment values for full and empty.
If an adjustment procedure fails, it is not necessary to again carry out
a level change.
These values can be helpful if the electronics has to be exchanged.

For min. adjustment the vessel should be as empty as possible, and
for max. adjustment, as full as possible. If the vessel is already full,
start with max. adjustment.
Note:
If possible, the vessel should be as empty as possible for min. adjust-
ment.
