This device produces readings in G, but G is not a constant value over the surface of the earth. What value of G, in m/s2, is represented by an output value of unity? Is 1G the value of the earth's gravitational field at the location at which the device is calibrated, or is it calibrated in m/s2 and 1G represents a constant, such as 9.81m/s2?

Hi handytech, what do you mean by "the last calibration"? We're quite interested in very precise gravity measurements that require using our locally estimated gravitational acceleration. Can we redo this calibration or is it only done at the factory? Is it possible to read out the stored constant or at least know what is used inside the sensors?
