Question

Hi team,

I have connected FMB 920 to laptop via USB and verifying the X, Y, Z values are changing every data packet when the device is stationary. Can you please provide details of angle and movement parameter documents to verify anything is wrong in the procedure

Hello,

Thank you for your query.

Could you provide what exact variation of value you are experiencing.  Usually axis value changes between 1-4 mG. Device Shows Axis in mG and this is very sensitive case. If you are using crash detection default threshold is set to 2.5G / 2500 mG.  Try using average constant to reduce these changes. By default device now register change on axis every 1 ms.  If avg constant will be set to 10 - 1 sec.

Average constant explanation can be found in Teltonika wiki page: https://wiki.teltonika.lt/view/FMB920_I/O_settings#Avg_Const

Let me know if you will still have questions.

Best Regards,
