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.
