between points A and B.

The instrument takes the backsight

stake out.

The instrument calculates the differ-
ence between the measurement and
the input value, and displays the result.

foresight reading.
If "Fill" is displayed, move the staff
upward.
If "Cut" is displayed, move the staff
downward.
When the display shows '0', you have
