Note!
The usable measuring range lies between the lower and the upper blocking distance. The values for
empty distance (E) and span (F) can be set independently of this.
Display (008)
The distance measured from the reference point to the product surface and the meas. value
calculated with the aid of the empty adjustment are displayed. Check whether the values
correspond to the actual meas. value or the actual distance. The following cases can occur:
• Distance correct – meas. value correct -> continue with the next function
"check distance" (051).
• Distance correct – meas. value incorrect -> Check "empty calibr." (005)
• Distance incorrect – meas. value incorrect -> continue with the next function
"check distance" (051).
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
