in the same way as described above.
③
Repeat the steps until all required known points are
input and measured.
④
Press [CALC] to calculate the coordinates of the
instrument station.
⑤
Press [ERR]. The standard deviation which
describes the measurement accuracy is displayed.

Caution:
In some cases it is impossible to calculate the coordinates of an unknown
point if the unknown point and three or more known points are arranged
on the edge of a single circle. If it occurs, try to take one of the following
：
a) Move the instrument station as close as possible to the center of the
triangle.
b) Observe one more known point that is not on the circle.
In some cases it is impossible to calculate the coordinates of the instrument
station if the included angle between the known points is too small. It is
difficult to imagine that the longer the distance between the instrument
station and the known points, the narrower the included angle between the
known points. Be careful because the points can easily be aligned on the
edge of a single circle.
