1 See Table, Steps 10 and 11.
2 See Table, Step 12.
3 See Table, Step 13.
4 Select the measuring mode if necessary:
• Select the "No linearization" option by means of the
Linearization/LINEARIZATION parameter.
• By means of the Primary Value Type/
PRIMARY_VALUE_TYPE parameter, select the
"Volume" option.
5 By means of the parameter Level Selection/
LEVEL_SELECTION select the "Level Easy Height".
6 By means of the parameter Output Unit Level Easy/
OUTPUT_UNIT_EASY select a volume unit, e.g. "1".
7 By means of the parameter Height Unit Level Easy/
HEIGHT_UNIT_EASY select a height unit, e.g. "m".
8 By means of the Calibration Mode Level Easy/
CALIBRATION_MODE_EASY parameter, select the
"Wet" option.
9 By means of the parameter Density Unit Level Easy/
DENSITY_UNIT_EASY select a density unit, e.g. "kg/
dm³"
10 By means of the parameter Adjust Density Level Easy/
ADJUST_DENSITY_EASY enter a density ,
e.g. "1" kg/dm³.
11 Fill the container up to the upper level point.
The related level value can be viewed via the Meas. level
easy/MEASURED_LEVEL_EASY parameter.
12 By means of the Empty height level easy/
EMPTY_HEIGHT_EASY parameter, enter a percentage
value, here 100% for example.
13 Fill the container up to the upper level point.
The related level value can be viewed via the Meas. level
easy/MEASURED_LEVEL_EASY parameter.
14 By means of the Full height level easy/
FULL_HEIGHT_EASY parameter, enter a percentage
value, e.g. 1000 "l".
15 Set the Pressure Transducer Block to the "Auto" block
mode.
16 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.
