34 VEGAMET 515
Adjustment example
You know the data of your sensor, i.e. you
know the sensor delivers at 0 % filling a cur-
rent of 4.2 mA and at 100 % filling a current of
15.5 mA. Enter these values in the menu
items.
7.2 Adjustment without medium
For the " Adjustment without medium“, two
anticipated levels, gauges etc., correspond-
ing to 0 % and 100 % must be entered.
Depending on the sensor type used, the
adjustment can be carried out in mA, bar or
m.
The menu item "Offset correction“ is activated
when connecting hydrostatic pressure trans-
mitters. The offset correction should be car-
ried out after installation of the sensors be-
cause the sensor values can differ slightly in
various installation positions (vertical or hori-
zontal mounting). With the offset correction,
the measured data of an unpressurized
sensor (vessel empty) are detected as a
corrective value and taken into account in all
all subsequent measurements.
In these two menu items, you enter the sen-
sor values. Use the [+] and [–] keys to set
the values and [OK] to save the values.
