Fig. 14: Calibrating the 2nd measured variable
3 See Table, Step 16.
4 See Table, Step 17.
5 See Table, Steps 18 to 21.
Enter the minimum level to be expected, here 0 m for
example.
12 Select the Level Max/LEVEL_MAX parameter.
Enter the maximum level to be expected, here 3 m for
example. See also Point 3 in the following note.
13 Select the "Dry" option via the Calibration Mode/
CALIBRATION_MODE parameter (calibration mode for
the 1st measured variable). See also Point 4 in the
following note.
14 By means of the Adjust Density/ADJUST_DENSITY and
Density Unit/DENSITY_UNIT parameters, enter a value
for the density, here 1 kg/dm
3
for example.
15 Result:
The calibration for the 1st measured variable is carried
out.
Perform linearization (calibration for the 2nd
measured variable)
16 Select the Scale Out/SCALE_OUT parameter, EU_0
element.
Specify the minimum tank contents to be expected, here
0 m
3
for example.
17 Select the Scale Out/SCALE_OUT parameter, EU_100
element.
Specify the maximum tank contents to be expected, here
5 m
3
for example.
18 By means of the Lin. Edit Mode/LINEARIZATION_
EDIT_MODE parameter, select the "Manual" option.
19 By means of the Table Selection/LINEARIZATION_
TABLE_SELECTION parameter, select the "Edit table"
option.
20 Enter the linearization table (min. 2 points, max.
32 points).
Table Line-Number/LINEARIZATION_TABLE_INDEX:
enter the value of the corresponding point.
X-Value/LINEARIZATION_TABLE_X_VALUE, 1st
element (X-value): enter the level, here 0 m for example.
Y-Value/LINEARIZATION_TABLE_Y_VALUE, 2nd
element (Y-value): Enter the volume value, here 0 m
3
for example.
21 You can enter further points for the linearization table as
explained in Step 19. The previous point first has to be
saved in the linearization table before the next point can
be entered. This means that complete linearization tables
cannot be saved in the device. Once all the points have
been entered, the table must be activated by means of
the Edit Table/LINEARIZATION_TABLE_POST_EDIT
parameter.
22 Set the Pressure Transducer Block to the "Auto" block
mode.
23 Where necessary, configure the Channel/CHANNEL
(→ ä 96), Linearization Type/L_TYPE (→ ä 97),
Transducer Scale/XD_SCALE (→ ä 95) and Output
Scale/OUT_SCALE (→ ä 96) parameters by means of
the Analog Input Block.
