Menu Structure Volume 3
5 Calculate Factor
Calculates the compensation factor resulting from the measuring
points in this menu.
This factor corresponds to the slope of the characteristic curve. The
calculated value is displayed in parameter
Comp Factor .
6 Comp Factor
Includes the compensation factor determined using this menu. It
compensates for differences in measurement sensitivity between
the level measurement and the gas density measurement.
7 Cal Rate Comp Table
Shows the read-in measuring points in a table ( Comp Table ) or a
characteristic curve ( Comp Curve ).

Calibration .
The menu contains functions to adjust the characteristic curve and
to take over older calibration data.
1 Adjust Lower Point
Use this feature only if you:
• replace the source, and a characteristic curve with several cali-
bration points has been entered.
• wish to calibrate the measurement with one calculated charac-
teristic curve and only one empty calibration, if necessary, with
a full calibration.
Changes in this menu affect the entire calibration curve and then
require enabling of
Adjust Curve LP and then Calibrate for the
changes to take effect.
2 Adjust Upper Point
Use this feature only if you want to adjust the entire calibration
curve with one calibration of the upper calibration point.
Changes in this menu affect the entire calibration curve and then
require enabling of
Adjust Curve LP and then Calibrate for the
changes to take effect.
If you want to specifically calibrate the upper calibration point, with-
out this affecting the other calibration points, you must calibrate
this measuring point in the
Cal Points menu.
