Event marker Button
The Event marker button on the device (marked
SAGA 32+ or SAGA 64+ depending on the
device type) can be used to set a marker event
in the STATUS channel. This marker event is
sampled synchronously to the other data.
Pressing this button also creates a trigger on the
synchronisation output of the device, this is a
configuration option in the application software.
Typical use of this button is to mark a specific event during an ambulatory
measurement, so this event can be looked up afterwards.
