Vertical Compensation
Vertical compensation maintains the
accuracy of vertical readings, since the
plate vial is perpendicular to the telescope
Grades / Slopes (%)
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
Can be turned off (TILT ON/OFF)(See
OPERATION AND DEMONSTRATION
section)
