Approx. 60 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.

Setup steps

After connecting VEGACAL 69 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 output 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 69 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 69 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:
