Distance = ok
Use this function for partially covered probes. Choose "manual" or "probe free" if the probe is free.
• Mapping is carried out up to the currently measured echo
• The range to be suppressed is suggested in the "range of mapping" (052) function
It is wise to carry out a mapping even in this instance.
Note!
If the probe is free, the mapping should be confirmed with "probe free".
Dist. too small
• At the moment, an interference echo is being evaluated
• Therefore, a mapping is carried out including the echoes currently measured
• 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 suppression
• Check 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
Mapping is also possible by manually entering 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.
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 definitely uncovered. Otherwise, the device will
not measure correctly!
Function "range of mapping" (052)
This function displays the suggested range of mapping. The reference point is always the reference
point of the measurement (s. Seite 47 ff.). This value can be edited by the operator.
For manual mapping, the default value is 0.3 m.
Function "start mapping"(053)
This function is used to start the interference echo suppression up to the distance entered in "range
of mapping" (052).
Options:
• Off: no mapping is carried out
• On: mapping is started
