The sensor is adjusted via the four keys of the display and adjust-
ment module. The LC display indicates the individual menu items. The
functions of the individual keys are shown in the above illustration.
Approx. 10 minutes after the last pressing of a key, an automatic reset
to measured value indication is triggered. Any values not confirmed
with [OK] will not be saved.
6.4 Setup steps
After connecting VEGACAL 62 to power supply or after a voltage
recurrence, the instrument carries out a self-check for approx. 30
seconds:
•
Internal check of the electronics
•
Indication of the instrument type, the firmware as well as the sen-
sor TAGs (sensor designation)
•
Output signal jumps briefly (approx. 10 seconds) to the set fault
current
Then the corresponding current is outputted to the cable (the value
corresponds to the actual level as well as the settings already carried
out, e.g. factory setting).
In HART-Multidrop mode (several sensors on one input) the address
must be set before continuing with the parameter adjustment. You
will find a detailed description in the operating instructions manual
"Display and adjustment module" or in the online help of PACTware
or DTM.

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 %
