Choose Zero in software.

Use the tools in the data-collection program to zero the sensor.<\/li>\n<\/ul>\n<p>If the force plate does not respond to a change in force, try connecting the sensor using the alternate method (USB or Bluetooth).

Call 888-837-6437 or email support@vernier.com.<\/p>\n<p class=\"has-very-light-gray-background-color has-background\">It is common for the force plate to exhibit some hysteresis (on the order of a few newtons) after hard impacts.

Generally, no. The sensor is set to the stored calibration before shipping. However, if your force plate readings are not consistent with expected readings, you may find calibration necessary.
