Using the Loupe
Use your finger to put the loupe in the pen down status. Position your line of sight
so that you are looking directly down into the loupe.
CAUTION: If you look through the loupe at an angle, the center point will be shifted and
you will not get a correct reading.
When aligning the loupe with a point, use the POSITION keys to move the loupe
so that the crosshairs are aligned with the center of the target point.
