TideMaster - Operating Manual: MANUAL-1094978189-1 | issue: 1.1
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.
