Adjusting Level Accuracy
1. When the accuracy of the Piper has been
checked, and the amount of error is known,
then the beam position is adjusted using the
UP and DOWN arrow buttons (c) to increment
the counter and move the beam to the
desired position.
Each count represents approximately two arc
seconds. Therefore, five counts of the counter
is approximately equal to 1.6 mm at 30 m
(1/16 inches at 100 feet).
2. The Piper icon will blink to indicate that the
unit has not reached the level position.
Use the LEFT or RIGHT arrow buttons (d) in
order to move the line during the procedure.
