1. The auto calibration procedure is automatic. It is completed when the Calibrate menu appears.
During calibration, the instrument seeks the high and low end points and the minor loop feedback (MLFB) and output
bias. By searching for the end points, the instrument establishes the limits of physical travel, i.e. the actual travel 0 and
100% positions. This also determines how far the relay beam swings to calibrate the sensitivity of the MLFB sensor.
