7.1.3.2 Moving Transducer Method
This is essentially the same as the Fixed Transducer Method, but does not require a waiting period between
level measurements:
High Calibration:
Enter the
High Tide Height
, either read from a calibrated Tide Board or staffing gauge relative to a known
datum.
At the highest expected tide, Enter the High Tide Height, either read from calibrated Tide Board or staffing
gauge relative to a known datum.
Press the
Get Reading
button
– TideMaster will sample pressure readings for 30s and record the high
height/pressure relationship.
Move the transducer up by a
known distance
, i.e. 400cm
Low Calibration:
Enter the Low Height value (subtract the
moved distance
from the
Measured High Tide Height
and input
into Low Tide Measurement)
Press the Get Reading button
– TideMaster will sample pressure readings for 30s and record the Low
height/pressure relationship
Once you are happy with the collected pressure/height readings the Generate button will calculate the
calibration factors and update the Gain and Offset parameters.
Return the Transducer to its
original position
.
