Operating the MC31XX 2 - 17
Free Fall Detection
IST continuously monitors gravitational force on the MC31XX according to its current position. When the MC31XX
free falls, IST detects the absence of gravitational force and records the event data if it detects a free fall more than
450 ms, which may indicate nearly a one meter drop. This data can be used as an indicator of potential abuse or
misuse.
IST features a log for recording the free fall events. This log records the date, time and the time period of the free
fall.
