Note that when using Part 2: Continuous Logging it will be necessary to zero the
level sensor in the collecting tank and to enter the initial mass of the collecting tank
when filled with water to obtain accurate results. These operations should be carried
out as follows:
Zeroing the Height Over Weir reading
At the start of an exercise it will be necessary to zero the reading for Height Over
Weir so that Out Flow Rate is correctly calculated. To zero the reading fill the
collecting tank until water flows out over lowest point of the weir. Wait for the level to
settle and stop flowing over the weir then press the Zero button. The Height and Out
Flow will then be set correctly to zero.
Zeroing the Mass reading
With Height Over Weir correctly zeroed and water at the lowest point of the weir with
no water flowing, note the Mass reading then type this value into the Initial Mass box.
The Mass reading will then be set correctly to zero so that Mass of Sand and
Sediment Yield will be correctly calculated during the exercise.
Operating the Equipment
