4.1. Operating Modes
Ra pid Mode
The rapidPro Profilers have a special mode designed for rapid profiling. Once the instrument is set into run mode:
No data is logged until a trigger depth is reached (e.g. 2 metres below the surface).
When the probe reaches the bottom of the profile and rises by a defined amount (e.g. 3 metres or more than the
local sea and swell) the profile file is closed and saved. This is referred to as the Trigger Step.
For a new profile to be started, the profiler must return to a depth of less than the Trigger Depth.
The time stamp stored in Rapid Mode files is defined as when the data was logged from, not when the file
was created.
Continuous mode
The rapidPro will log data at the defined rate from when the instrument is set into run mode or switched on.
Data will be logged at that rate until the instrument is interrupted or switched off.
When used in conjunction with Connect software, the rapidPro can be operated in an automatic mode, where the
presence of the unit on the surface is recognised, after a profile has been observed and that data file is recovered
through Bluetooth.
