Install a reflector prism on the tripod at Point P.
5.
Set up another tripod at Point R, on the line between Point P and Point Q.
6.
Transfer the NPL-322 instrument to the tripod at Point R.
7.
Measure the distance from Point R to Point P (RP), and from Point R to
Point Q (RQ).
8.
Calculate the difference between the value of PQ and the value of RP + RQ.
9.
Move the NPL-322 to other points on the line between Point P and Point Q.
10. Repeat

ten times or so.
11. Calculate the average of all the differences.
The error range is within 3 mm. If the error is out of range, contact your dealer.
Checking the Laser Pointer
The NPL-322 series total station uses a red laser beam to measure and as a laser
pointer. The laser pointer is coaxial with the line of sight of the telescope. If the
instrument is well adjusted, the red laser pointer coincides with the line of sight.
External influences such as shock or large temperature fluctuations can displace the
red laser pointer relative to the line of sight.
