If you know the level at a certain height, you can enter in this menu
item the determined real level to correct the measured value. The
function shifts the linearization curve to this determined point.
With this procedure the measurement can be adapted exactly to the
conditions in the vessel.
In this menu item you can activate or deactivate the current output.
The MINITRAC 31 checks if with activated current output there is re-
ally an instrument connected.
If no instrument is connected to the current output, you have to deacti-
vate the current output.
In this menu item you can define the characteristics of the sensor and
its behaviour in case of a fault.
In this menu item you can define the behaviour of the current output.
You can determine the current with min. and max. level separately.
In this menu item you can activate the relay output and determine its
function as well as the switching points.
When the output of the process values is set, you can choose be-
tween overfill and dry run protection.
The relay outputs of the sensor react accordingly.
