6. Setup → Tube diameter (only for "Tank type" = "Bypass / pipe")
 Specify the diameter of the bypass or stilling well.
7. Setup → DC value
 Specify the dielectric constant of the upper medium
8. Setup → Empty calibration
 Specify the empty distance E (distance from the reference point R to the 0% mark).
9. Setup → Full calibration
 Specify the full distance F (distance from the 0% mark to the 100% mark).
10. Setup → Level
 Displays the measured level L
L
.
11. Setup → Interface
 Displays the interface height L
I
.
12. Setup → Distance
 Displays the distance D
L
between the reference point R and the level L
L
.
13. Setup → Interface distance
 Displays the distance D
I
between the reference point R and the interface L
I
.
14. Setup → Signal quality
 Displays the signal quality of the analyzed level echo.
15. Setup → Mapping → Confirm distance
 Make sure the vessel is completely empty. Then select Tank empty option.
NOTICE
Wrong measurement due to incorrect dielectric constant of the lower medium
‣
If, for Operating mode = Interface with capacitance , the lower medium is not water, the
dielectric constant (DC value) of the medium must be specified: Setup → Advanced setup →
Interface → DC value lower medium
NOTICE
Wrong measurement due to incorrect empty capacitance
‣
In the case of rod and rope probes in the bypass and if Operating mode = Interface with
capacitance , a correct measurement is only possible once the empty capacitance has been
determined. For this purpose, select Confirm distance = Tank empty after installing the
probe when the tank is completely empty (Step 13 in the table above).
The empty capacitance is always calibrated ex works in the case of coax probes.
