The measurement direction of the accelerometer must be referred to the tach sensor position. This can be done by the "Angular correction" in the analyzer setup. In our example in '''Sketch 1,''' the '''angular correction''' is '''90°''' and the <font color="#339966">'''offset''' is -'''15 °'''. | The measurement direction of the accelerometer must be referred to the tach sensor position.
