Function "check distance" (051)

This function triggers the mapping of interference echoes. To do so, the measured distance must be
compared with the actual distance to the product surface. The following options are available for
selection:
Selection:
• distance = ok
• dist. too small
• dist. too big
• dist. unknown
• manual
• probe free
distance too small
+
distance = ok
Use this function at part-covered probe. Choosing function "manual" or "probe free" at free probe.
• 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.
Note!
At free probe, the mapping should be confirmed with the choice "probe free".
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.
