7.4 Update Rate
You may set the rate at which the 350 system supplies measurements to an external data logger to
either one or four records per second.
Update rates available from independent seabed profiling systems may be different from the update
rate you have set for the 350 system. If your ROV includes both these systems, you must allow for their
different update rates when you analyse the survey data.
