distance = ok
• Mapping is carried out up to the currently measured echo.
• The range to be suppressed is suggested in the "range of mapping" (052)
function.
Anyway, it is wise to carry out a mapping even in this case.
dist. too small
• At the moment, an interference is being evaluated.
• Therefore, a mapping is carried out including the presently measured echoes.
• The range to be suppressed is suggested in the "range of mapping" (052)
function.
dist. too big
• This error cannot be remedied by interference echo mapping.
• Check the application parameters (002), (003), (004) and "empty calibr." (005).
dist. unknown
If the actual distance is not known, no mapping can be carried out.
manual
A mapping is also possible by manual entry of the range to be suppressed. This entry is
made in the
"range of mapping" (052) function.
"
Caution!
The range of mapping must end 0.5 m (20 in) before the echo of the actual level. For an
empty tank, do not enter E, but E - 0.5 m (20 in).
7.3 Function "range of mapping" (052)
This function displays the suggested range of mapping. The reference point is always
the sensor membrane. This value can be edited by the operator.
For manual mapping, the default value is: 0 m.
7.4 Function "start mapping" (053)
This function is used to start the interference echo mapping up to the distance given in
"range of mapping" (052) .

Caution!
If a mapping already exists, it is overwriten up to the distance specified in
"range of mapping" (052) . Beyond this value the existing mapping remains
unchanged.
