Procedure •  Record the current Level Value before the mounting 
change.
•  Change the mounting from Top to Bottom or vicer 
versa.
•  Change the Signal Polarity in the Diagnostic Menu 
(typically Standard for bottom mount and Reversed 
for top mount)
•  If the points were just swapped and kept in the 
versa), the level indicated might deviate between 
mounting orientation but if the the points were 
physically displaced up or down the deviation might 
be larger.
•  Calculate the deviation of the level reading between 
previous and new mounting.
•  There are two ways to handle this:
add the determined deviation
- Apply Offset. Notice that when the Offset is 
used it leaves behind the LRV & URV, which need 
to be set again.
• End
