4.10. Measurement of tilt and distance
This measurement allows for an evaluation of the tilt
with respect to the horizontal by means of an internal
sensor and of the distance between two points through
trigonometric calculation. For accurate measures we
recommend using a tripod
1. With the instrument in stand-by, press the key to
select the desired type of reference (see § 4.2)
2. Press the key to enter the indirect 3-point
measuring section. The symbol “ “ appears on
the display with side “1” flashing
3. Position the instrument in the point (1)
corresponding to the value of the desired measuring
angle “
“ (varying between ±65° with transversal tilt
not higher than ±10°) shown on the first display and
press the key or the side MEAS key (see Fig.
12)
4. The value of distance “1” is shown on the resulting
display. The value of distance “a” is shown on the
third display, calculated as: a = (1)* cos
. The value
of distance “b” is shown on the second display,
calculated as: b = (1)* sen
 (see Fig. 12)
5. Measuring result is automatically saved in the
instrument's memory

4.11. Operations with the memory
The instrument is provided with a memory section in
which it is possible to recall measuring results. It is
possible to save up to 20 measurements, shown in
reverse order.
 Use the keys
or for internal navigation.
 Press the keys and at the same time to
