8.3 Drawn quantity
Instead of the level, the drawn quantity should be
displayed.
Again 4..20 mA is chosen as input range. Assign
10 as „displayed value at min.
input signal" to the lowest input level (5 mA) and
0 as „displayed value at max. input signal"
(19 mA).
8.4 Level measurement with limited
display range
A third example is level measurement with limit-
ed display range, that means a tank with 10 m
have to be filled up at best to 8 m
should not decrease below 1 m
3
> 8 m
the display is to show „hi" and at values
3
< 1 m
the display is to show „lo". 4..20 mA is
chosen as input range.
Assign 0 as „displayed value at min. input signal"
to the lowest input level and 10 as „displayed va-
lue at max. input signal"to the highest input level.
Additionally, program for menu item „min. input
signal", the value of which corresponds to the

1 m
level, e.g. 5.6 mA. Do the same for menu
item „max. input signal" with the value which cor-
3
responds to the 8 m
At input levels > 16.8 mA „hi" will be displayed
and at input levels < 5.6 mA „lo".

and its level

level, e.g. 16.8 mA.
Max. input
voltage or
max. input
current can
be shifted

range
Displayed value can be freely
adjusted to the input value
