You can change the reference point from which level is measured. Use the menu item2.3.8 Tank 2.3.8 Tank 2.3.8 Tank 2.3.8 Tank
Bottom Offset Bottom Offset Bottom Offset Bottom Offset. If you move the reference point below the tank bottom, add this value when give a
level for the 4 and 20 mA current output settings. If you move the reference point above the tank
bottom, subtract this value when you give a level value for the 4 and 20 mA current output
settings.
For more data about the menu items, refer to
Function description on page 79.
6.4.7 How to configure the device to measure volume or mass
The device can be configured to measure volume and mass. You can set up a strapping table in
the 1.2.0 Conversion Setup
1.2.0 Conversion Setup 1.2.0 Conversion Setup 1.2.0 Conversion Setup procedure or the 2.8.0 Conversion Table 2.8.0 Conversion Table 2.8.0 Conversion Table 2.8.0 Conversion Table menu. Each entry is a pair of
data (level
–
volume or level
–
mass). The strapping table must have a minimum of 2 entries and
a maximum of 50. The reference point for the table is the bottom of the tank (as given in menu
item 2.3.1 Tank height
2.3.1 Tank height 2.3.1 Tank height
2.3.1 Tank height).
CAUTION!
If the level for 20 mA is set in the blocking distance, the device will not be able to use the full
current output range.
