11.2 Triggers
While the Odometer trigger is self-explanatory, the other Trigger Methods require a brief
description below:
11.2.1 Manual / Bluetooth
If the Trigger Method (6.2.3) is set to Bluetooth or manual DVL, the following data collection
sequence is followed:
a) Set the antennas at the correct separation and centred on the starting position for the
survey line.
b)
The data collection screen on the DVL should display “Press Trigger”.
c) The operator presses the up or down button on the DVL, or they can use the Bluetooth
trigger.
d) The system starts to beep, indicating the data trace is being collected. The antennas
should be kept in contact with the ground surface while the system is beeping.
e) When the beeping stops, one trace has been collected.
f)
Move the antennas together along the survey line a distance equal to the Step Size
distance.
g) Repeat from step b)
