This application is designed to measure the g force imposed on a component when it's dropped. It measures 3 channels simultaneously so you can use an accelerometer in 3 locations, but more commonly you'd use the 3 channels for each axis of a triaxial accelerometer. This way, if the orientation of the component changes during free-fall, you can still calculate the overall g force. In fact, our software does that for you and exports the total g force, regardless of accelerometer positioning, into Excel along with the individual channel g forces.
