7. Setup → Empty calibration
Enter the distance E between the reference point R and the minimum level (0%).
8. Setup → Full calibration
Enter distance F between the minimum (0%) and maximum (100%) level.

13. Setup → Signal quality
Displays the signal quality of the level echo.
14. Setup → Mapping → Confirm distance
Make sure the vessel is completely empty. Then select the Tank empty option.
NOTICE
Wrong dielectric constant of the lower medium may cause a measuring error.
‣
If in the case of Operating mode = Interface with capacitance the lower medium is no
water, it is necessary to specify its dielectric constant (DC value): Setup → Advanced setup
→ Interface → DC value lower medium
NOTICE
Wrong empty capacity may cause a measuring error.
‣
For rod and rope probes with Operating mode = Interface with capacitance, a correct
measurement is only possible after the empty capacity has been determined. To do so,
make sure that the vessel is completely empty. Then select Confirm distance = Tank
empty (Step 13 in the table above).
For coax probes the correct empty capacitance is always set on delivery.
