Indirect Measurement
In the Indirect Measurement mode,
the tool measures one angle and
one side of a right triangle and
used trigonometry to compute the
distance that cannot be measured
because of obstruction by an
obstacle or the unavailability of a
reflecting target surface.
1. Press UP Arrow Button or Down
Arrow Button to change the
mode to the indirect measurement. The LCD will display "Indirect"
on the lower right.
2. Press the Main Button to turn on the laser if it is not turned on;
both the Laser Indicator and the icon
3. Position the tool
aim the laser at the target B. The real-time angle of
automatically show in first row of the display. (FIG. 10)
4. Without changing the measuring reference point of the tool in
position A, aim the laser at point B and press the Main Button.
Ensure that the tool is level and square when taking this
measurement.
The calculated length of AC will appear in the second row of the
screen with prefix "a=", The calculated length of BC will appear in
the third row of the screen with prefix "b=", and the measured length
of AB will appear in the lowest row of the screen (FIG. 10).
