5 Select the "Editor table" option by means of the TABLE
SELECTION parameter.
6 Select the "Manual" option by means of the LIN. EDIT
MODE parameter.
7 Select the "New table" option by means of the EDITOR
TABLE parameter.
8 Enter the linearization table (min. 2 points, max.
32 points).
LINE-NUMB: Confirm value displayed.
X-VAL.: enter the pressure value and confirm.
Y-VAL.: Enter the volume value, here 0 m
3
for example,
and confirm.
9 Local operation:
If you want to enter another point for the linearization
table, select the "Next point" option and enter the point
as described in Step 8.
If you want to finish entering the values and activate the
linearization table, select the "Accept input table" option.
FieldCare:
You can enter further points for the linearization table as
explained in Step 8. Once all the points have been
entered, the table must be activated by means of the
TAB. ACTIVATE parameter.
10 Where necessary scale the OUT value of the Analog
Input Block, see Page 93 parameter descriptions. For this
purpose, equate XD SCALE and OUT SCALE or the OUT
value with the measured value.
11 Result:
The linearization table has been entered and the device
is ready for level measurement.
