Information:

The zero adjustment shifts the value of the span adjustment. The

span, i.e. the dierence between these values, however, remains

unchanged.

Information:

For an adjustment with pressure, simply enter the actual measured

value indicated at the bottom of the display.

If the adjustment ranges are exceeded, the message "Outside param-

eter limits" appears. The editing procedure can be aborted with [ESC]

or the displayed limit value can be accepted with [OK].

Proceed as follows:

1. Edit the mbar value in the menu item "span" with [OK].

Span

100.0 %

+1000.0 mbar

0000.0 mbar

Information:

The displayed pressure for 100 % corresponds to the nominal meas-

uring range of the sensor (in the above example 1 bar = 1000 mbar).

2. Set the requested mbar value with [->] and [OK].

3. Conrm with [OK] and move to the menu overview with [ESC].

The span adjustment is nished.

Information:

A linearisation is necessary for all vessels in which the vessel volume

does not increase linearly with the level - e.g. in a horizontal cylindri-

cal or spherical tank - and the indication or output of the volume is

required. Corresponding linearisation curves are preprogrammed for

these vessels. They represent the correlation between the level per-

centage and vessel volume. By activating the appropriate curve, the

volume percentage of the vessel is displayed correctly. If the volume

should not be displayed in percent but e.g. in l or kg, a scaling can be

also set in the menu item "Display".
