If you point the accelerometer sensitive axis (see data sheet) down or up, you will get + and - 1g. Useful for calibration. > Cross-Axis Sensitivity 12 % The device in question is a dual accelerometer. Its 2 accelerometers measures acceleration in 2 axes nominally at right angles to each other. However each has a small reponse to acceleration along the direction (axis) at right angles to its own axis - cross axis sensitivity. > Noise Density residual noise expressed in spectral terms. Can be reduced by suitable low pass filter. > Acceleration (Any Axis, Unpowered for 0.5 ms) . . . . . . 1000 g beyond this the device will be permanently damaged. ie the silicon breaks ! > Acceleration (Any Axis, Powered for 0.5 ms) . . . . . . . . . . 500 g as above. > > Thanks and have a nice day. > > Rgds, > Pang > > -- > http://www.piclist.com#nomail Going offline?
