4.8. Indirect 2-point measurement
Indirect measurement allows precisely evaluating a
distance between two points on a vertical wall (height)
exploiting the mathematical principle of the
Pythagorean theorem. 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 2-point
measuring section. The symbol “ “ appears on the
display with side “1” flashing
3. Position the instrument in the highest point (1) of
measurement (see Fig. 9) and press the key
or the side MEAS key to measure. The result
appears on the first partial display. The symbol “
“
appears on the display with side “2” flashing
4. Position the instrument as horizontally as possible
(2) (see Fig. 9) and press the key or the side
MEAS key to measure. The result appears on the
second partial display
5. The final value of the result (obtained as
2 2 ) 2 ( ) 1 (

)
is shown on the resulting display
6. Measuring result is automatically saved in the
instrument's memory
