F.2.3 Present depth
If the Bottom Reference is unknown but the present liquid depth is known,
the transmitter can set the Transmitter Bottom Reference value using the Present Depth value,
the live Distance measurement, and optional offsets:
P010 = (Depth + D910) - (P060 + P069)
Where:
P010= Transmitter Bottom Reference (see page 136).
Depth= Present Depth setting (live level value snapshot but can be edited).
D910= Distance measurement (see page 199).
P060= Distance Offset (see page 141).
P069= Level Offset (see page 142).
