F.2.3 Present depth
If the Bottom Reference is unknown but the present liquid depth is known , the transmitter can
set the Bottom Reference value using the Present Depth value, the live Distance
measurement, and optional offsets:
P010 = ( Depth + D910 ) - ( P060 + P069 )
Where:
P010= Bottom Reference (see page 105 ).
Depth= Present Depth setting (live level value snapshot but can be edited).
D910= Distance measurement (see
page 153 ).
P060= Distance Offset (see page 109 ).
P069= Level Offset (see page 110 ).
