I have two questions on ADIS16228 Datasheet Rev.B.
- Page 3: Is Clock Accuracy of 3% typ. includes clock tempco? How much contribution can we expect for tempco error among it?
- Page 15: "Scale Adjustment" section, it says "The calibration process records accelerometer output in four different orientations ...". Why it is not three direction but four direction? What exactly is the direction other than x, y, z?
