The accelerometer is designed to measure the force of acceleration along the selected axis. Make sure you choose the correct range and axis for the practical.

A hook / hoop is supplied to screw into the end of the sensor. Take care to not over tighten the screw or there is a possibility the end cap will split. Use the white locking nut to secure the hoop into place.

Constant rotational force is measured as the diameter of the rotation increases. If you try this practical, ensure the string is tied very securely to the hoop and rotate only with sufficient force to keep the sensor rotating parallel to the floor. If excessive rotation force is used there is a possibility the screw thread will separate from the end plate.

  • Attach the sensor firmly to the object under test. Use cable ties or low tack masking tape (the tape can be removed without leaving glue residue on the sensor).
  • The accelerating object should weigh more than the Accelerometer (which weighs approximately 28 g). 
  • Use no more than the sensor length to drop the sensor directly onto a solid surface, as higher drops may result in extreme jarring that could damage the sensor.  
  • If the low g Accelerometer’s Resultant range is selected to record a vehicle’s journey, it uses data from all 3 axes; this will include any bumps or vibrations which may confuse results. 
  • The sensor is not waterproof.
  • Be careful when cleaning. Use methylated spirit or isopropyl alcohol, not acetone or other solvents known to dissolve plastic.
  • If you hang items from the hoop screwed into the front plate do not exceed 2 kg.
  • If you whirl the sensor around, make sure the forces generated do not exceed the carrying capacity of the captive thread nut in the face plate, and ensure the thread connected to the sensor is securely connected.
