the faces toward each other. Position and level the instrument so that the distance from the
instrument to each rod is the same (measure; Fig. 2).
Take a reading on each rod with the instrument (or mark each piece of strapping where the
crosshair is sighted). Note the difference and record them. Next, move the instrument to another
point in line with the two level rods as shown in Fig. 3. Level the instrument and take readings on
the two level rods (or re-mark the two pieces of strapping with the new crosshair sightings). The
differences should be the same ( A - A'should equal B - B'). The difference between A - A' and B -
B' is the instrument error at 200 feet.
Correction of instrument error should be performed by a competent repair technician.
The instrument should be rechecked periodically to assure continued accuracy.
