Congratulations! 

You are off and running!  MicroStrain Support Engineers are always available by phone, email 
or SKYPE to assist you in any way we can. 

 

 

Caution 

Do not bring the 3DM-GX3

®

 into contact or close proximity with magnets. Magnets will at a 

minimum disrupt the sensor’s operation and can cause permanent damage to its components.  
Many GPS antennas have a magnetic base; the antenna we provide does not. If you substitute a 
GPS antenna and its base is magnetic, please keep it away from the 3DM-GX3

®

 (and don’t pack 

them together).
