Level Values
Volume Values
Enter up to 32 level breakpoints, where the corresponding volume is
known. The values corresponding to 100% and 0% levels must be entered.
The breakpoints can be ordered from top to bottom, or the reverse.
Example (values are for example purposes only)
2.2.2.6.1.
2.2.2.6.2.
2.2.2.6.3.

The default for level values is percent: if you want to select units
instead, navigate to Input (2.2.) > Sensor Calibration (2.2. 1 .) > Unit
(Level) (2.2.1.6.), and select the desired unit
Navigate to Input (2.2.) > Volume conversion (2.2.2.) > PV (volume/
level) Units (2.2.2.1.), and select the desired volume units.
Go to XY index (2.2.2.6. 1 .) and enter the number of the breakpoint you
wish to adjust: for example, for breakpoint 1 enter 1.
Go to X value (2.2.2.6.2.) and enter the level value for the breakpoint
just identified.
Go to Y value (2.2.2.6.3.) and enter the volume value for the
breakpoint just identified.
Repeat steps (c) to (e) until values have been entered for all required
breakpoints.
