Possible cause
See table of error messages (see page 79)
Measured distance (008) OK?
Remedy
1.See table of error messages (see page 79)
yes → 1. Check empty calibr. (005) and full calibr. (006).

Is an
FAR 10 antenna extension being used?
no ↓
An interference echo
may have been evaluated.
2. Check linearization: |
→ level/ullage (040) |
→ max. scale (046) |
→ diameter vessel (047) |
→ Check table |
yes → 1. Is bypass or stilling well selected
in tank shape (002)?
2.Is the pipe diameter (007) correct?
yes → 1. offset (057) correctly set?
yes → 1. Carry out tank mapping
→basic setup
No change off measured value on filling/empty- ing

Interference echo from installations, nozzle
or extension on the
antenna
1.Carry out tank mapping → basic setup
2.If necessary, clean antenna
3.If necessary, select better mounting position
