Dual-face Measurement In the dual-face mode, the program will prompt for
measurements in both faces. When both measurements
are taken, the program will check the difference
between the two. If the difference in angle is within 27'
(0.5 gon) and the difference of two measured distances
is within 0.5 m (1.64 ft), the observations will be
averaged. These tolerances are used to avoid errors in
target identification. If exceeded an error message will
be displayed.
