Indirect measurement
The instrument can calculate distances using
Pythagoras’ theorem.
)
Make sure you adhere to the prescribed
sequence of measurement:
• All target points must be in a horizontal or vertical
plane.
• The best results are achieved when the instru-
ment is rotated about a fixed point (e.g. with the
positioning bracket fully folded out and the
instrument placed on a wall).
• The minimum/maximum function can be used -
see explanation in "Measuring -> Minimum/
maximum measurement". The minimum value
must be used for measurements at right angles to
the target; the maximum distance for all other
measurements.
)
Make sure that the first measurement and the
distance to be measured are at right angles. Use the
Minimum/maximum function, as explained in
"Measuring -> Minimum/maximum measurement".
Indirect measurement - determining a dis-
tance using 2 auxilliary measurements
e.g. for measuring building heights or widths. It is helpful
to use a tripod when measuring heights that require the
measurement of two or three measurements.
Press this button once, the display shows .
The laser is switched on.
Aim at the upper point (1) and trigger the
measurement. After the first measurement the value
is adopted. Keep the instrument as horizontal as
possible.
Press and hold down this button to trigger
continuous measurement, sweep the laser back and
forth and up and down over the ideal target point.
