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

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".
