calculation is available and the soft key „Calc‟ appears on the
screen. Press „Calc‟ to display the area and circumference of the
enclosed shape. Press „ESC‟ to quit the area survey.
How to input coordinates:
Press soft key „Input‟ and enter „Point/Area‟ page
Press „F2‟ to list out all coordinates in the current
measurement file. Press „F3‟ to list out all coordinates in the

Prism A（0,0,0）
This function is used to measure the length (X) of the prism
point deviation from the starting point of baseline ,distance(Y) of
the prism point deviation from baseline,and altitude difference
(Z)of the prism point deviation from the starting point of
baseline.
The preparation before measurement is: setting up the
instrument height, the target height and defining the baseline.
Define baseline: Press soft key „Meas‟ under the page of
„Project(Begin)‟ to start measurement. After the measurement of
begin point, press soft key „Enter‟ to measure the end point,
following the steps of measuring begin. Finally, press soft key
„Enter‟ to end the defining of the baseline. Now you may start
projecting.
