If the HA corr. setting is set to OFF, the ACH parameter is not applied to
horizontal angle readings. If this setting is set to ON, both of the ACH
and trunnion-axis parameters are applied to HA. If you do not complete
the second step, the trunnion-axis parameter remains set to zero, and
only the ACH parameter is applied. If ACV, ACH, X, or Y is out of range,
OVER appears. Press any key to return to the first observation screen.
