accuracy of vertical readings, since the
plate vial is perpendicular to the telescope


 Steep slope

Sometimes Vertical Compensation can
create problems

Demos: The instrument MUST be leveled before
demonstrating, and “TILT” is displayed when the
instrument is moved around

Compensation causes an error when a precise
vertical angle between two vertical points is
being measured
