Accelerometer auto calibration functionality has one purpose - determine how {{{model|FMC}}} device is mounted in a vehicle. After the calibration process ''eco driving'' functionality becomes active and calibration data will be used to determine harsh acceleration, braking and cornering events.

There are two conditions when auto calibration takes place:

Then first vector is taken. Saved vector will be considered as ground vector and it will be used at further calibration calculations.

''Note: When FMC device saves first ground vector vehicle must be parked on flat ground''. Crooked vector may have an impact on further calculations.

If ignition (DIN1 or Power Voltage) is ON and the vehicle is not moving, FMB640 will generate the ''Excessive Idling'' event when the configured time period passes. When vehicle starts moving and configured period of time passes, FMB640 will generate event that vehicle idle time ends. Auto Geofencing option can be configured by the following parameters:

If ignition (DIN1 or Power Voltage) is ON and the vehicle is not moving, {{{model|FMC640}}} will generate the ''Excessive Idling'' event when the configured time period passes. When vehicle starts moving and configured period of time passes, {{{model|FMC640}}} will generate event that vehicle idle time ends. Auto Geofencing option can be configured by the following parameters:

*Time to stopped - scenario is activated until vehicle starts moving and keeps moving (moving is detected only from the accelerometer) for the amount of time that is configured.

If accident happens and FMC640 detects acceleration value higher than set threshold value during set time period, then device will generate an event. Threshold and duration values are set depending of accident power which you want to detect. FMC640 can detect a slight tapping on the device (Threshold=100mg, Duration=1ms) or can detect severe accident (Threshold=4000mg, Duration=5ms).
