3.6.4 Mode transition diagram
The supported mode transitions are displayed below. If the device is currently performing a
measurement, execution of mode switching commands is delayed until the end of the currently
running measurement period. Further mode change commands are ignored until the last mode
change command is executed. Mode transitions other than the ones shown below are tested for
stability but do not represent recommended use of the device.
