Diagnostics and troubleshooting
Solution
Deactivate echo tracking (Expert
→ Sensor → Echo tracking → Evaluation
mode = History off).
Enter a new value for the Empty
calibration parameter (→  114).
• Perform a probe length correction
(Confirm probe length parameter
(→  143)).
• Carry out mapping over the entire
probe length when the tank is empty
(Confirm distance parameter
(→  117)).
Select the correct Bin type parameter
(→  113).
