The  accelerometer  is  a  mechanical  structure  that  contains  components  that  can  move  freely.  These  moving  parts  are  very  sensitive  to 

mechanical  stress,  far  beyond  solid-state  electronics.  The  0g  offset  or  offset  is  an  important  accelerometer  indicator  because  it  defines  the 

baseline used  to  measure acceleration.  After the device is installed, it will be turned on.  After 1 minute of network access, the device will 

automatically offset the calibration. If the device installation position moves, you need to power off the device after a complete power off for 

one minute.

 

 
Data report configuration and sending period are as following: 

 

 

 

 

 

 

 

 

 

Example#1

    based on MinTime = 1 Hour, MaxTime= 1 Hour, Reportable Change i.e. BatteryVoltageChange=0.1V

Note: MaxTime=MinTime. Data will only be report according to MaxTime (MinTime) duration regardless BtteryVoltageChange value. 

 

Example#2 

  based on MinTime = 15 Minutes, MaxTime= 1 Hour, Reportable Change i.e. BatteryVoltageChange= 0.1V.
