"reduced menu“ (see appropriate chapter).

The menu items "

Density…

DK value…

are displayed as options when under "Con-
figuration measurement loop“ the appropriate
sensor type has been selected. The density
or DK value must, before adjustment with
medium, be so adjusted that it corresponds
to the value of the medium (water has a den-
sity of 1.0 kg/dm

3

and a dielectric value of

81.00).

The following linearisation curves are avail-
able:
- linear (factory setting)
- horiz. cylindrical tank
- spherical tank
- Lin-curve 1
- Lin-curve 2
- Lin-curve 3

Lin-curves 1 … 3 can be edited by the
user (see appropriate chapter).

After scaling or linearisation, the required
output must be assigned to the scaled or
linearised value (menu item "prop. to..." and
"Unit...") in the menu range "Parameter adjust-
ment of outputs".

Under

Meas. value limitation,

you can ex-

clude negative values.

Failure mode Standard

means that at a sensor current of 3.6 mA or
21 mA, the fail safe relay responds.

Failure mode >110%

generates a fault signal if a meas. value of
more than 110 % or less than -10 % is
reached.
