3.2.2 Real-Time Tab (View Level TROLL Readings)
When connected, the real-time view will show the current readings from all of
the connected Level TROLL instruments in one screen.
The Depth and the Level values are shown on the real-time screen. This can
help operators ensure that the Level TROLL instruments are still under water
as the water level drops.
