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 67 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 67 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 %
