NOTE
Slope ratio should be given.
Slope ratio can be determined by using the
given horizontal scale and vertical scale.
(9) Press CLEAR button to clear auto-scaler.
(10) Trace boundary of shape using dot in lens tracing assembly. Stop when
you reach the starting point.
(11) Press foot switch to activate PRINT command and freeze count.
NOTE
Calculator will print area of shape.
Horizontal area in square feet will
be printed first followed by the true surface area in square feet.
(12) Keeping foot switch depressed, reposition planimeter near next shape to
be measured.
(13) Repeat steps (9) through (11).
