Notes:
• Setting P006 resets Span, if it has not
previously been set to a different
value.
• The default setting for Span is based
on Operation (P001) and Empty (P006).
Span is set to Empty minus 110% of
Blanking distance
set to distance (P001=3). In this case,
Span is set to Empty distance.
• Always prevent the monitored surface
from approaching within 0.3 m (1 ft) of
the reference point, as this is the
minimum distance detectable.
