Current Slew Rate Percentage

Calibrate Home Index Offsets
In rare cases, the home position may not be consistent due to small changes in the mechanical position of the
home sensor and homing mark caused by temperature variations. In this case, the home position can differ by
one turn of the motor when the mount is homed (from 3 to 6 arcminutes, depending on mount model and axis).
On the Bisque TCS window, highlight Calibrate Home Index Offsets on the left side of the Utilities tab and click
the Calibrate Home Index Offsets button to have the control system measure the motor’s home index offset.
