Commissioning
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 0.3 m (20") before the echo of the actual level. In case of empty
vessel it is possible to make a map over the whole probe length.
probe free
If the probe is uncovered, mapping is carried out along the whole probe length.
"
Caution!
Only begin mapping in this function if the probe is safely uncovered. Otherwise, the device will
not make correct measurements!
5.4.15 Function "range of mapping" (052)
ENDRESS + HAUSER
–
+ E
This function displays the suggested range of mapping. The reference point is always the
reference point of the measuremen (→ ä 28). This value can be edited by the operator.
For manual mapping, the default value is 0,3 m.
