How do I zero a force measurement on a Wireless Force/Acceleration Sensor? It is important to make sure that a force sensor is properly warmed up prior to zeroing the sensor. After the sensor has been warmed up, collect a run of data to make sure that the sensor is close to zero. Zero the sensor by clicking on the live data tab, and click on zero sensor. When you do this, make sure that the sensor is in the orientation in which the sensor will be used. Next, while collecting data, attach any accessories to the force sensor that will be used during the experiment. Note any changes from the zero that was established before. If you notice any changes that remain when you are no longer affixing the accessory, back out the attachment 1/4 turn. This should remove any preload from the sensor.
