1) When centering with two scanning heads
2) Position error within one signal period and the accuracy of the graduation together result in the encoder-specific error; for additional error from mounting and bearing of the measured shaft, see Measuring accuracy in the brochure Modular Angle Encoders with Optical Scanning
