TROUBLESHOOTING
- Primary Test: Open the data-collection program and start a new experiment file. Connect the force plate to the software using the USB cable or Bluetooth. Using the default channel (Force), does the plate read approximately zero? Choose Zero in software. Stand on the plate; using F=mg, does the reading make sense?
- Secondary Test: Changing the physical orientation of the sensor will change the reading when no force is applied. Use the tools in the data-collection program to zero the sensor.
If the force plate does not respond to a change in force, try connecting the sensor using the alternate method (USB or Bluetooth). Verify that the battery is charged sufficiently. If plate still does not respond, contact Technical Support. Call 888-837-6437 or email support@vernier.com.
It is common for the force plate to exhibit some hysteresis (on the order of a few newtons) after hard impacts. This can be accounted for simply by zeroing the sensor.
If you determine that calibration is needed to get accurate data from your force plate follow these tips:
- The weight should be at least 25% of the range.
- Take care to accurately center the weight on the force plate. Due to the combining of 4 load cell signals, this has a significant impact on the results of calibration.

CALIBRATION
- Calibrate? No. The sensor is set to the stored calibration before shipping.
If you wish to calibrate the sensor, you will conduct a two-point calibration. The first point is zero. Set the Force Plate on a level surface and remove all force from the Force Plate. Enter 0 (zero). Second point: apply a known force (known mass) to the Plate. To obtain a good calibration, the weight should be at least 25% of the range used for the plate (850 N) if possible. Enter the weight of the mass (note: 1 kg weighs 9.8 N). Be careful not to exceed the selected range setting during the calibration.
