Area measurement
1. Press the mode key
to choose the area-measurement mode; the mode icon
will
blink on the lcD screen.
2. Press the measure key
to turn on the laser beam; position the tool to aim the laser dot at
the target to which you want to measure.
3. Press the measure key
to take the first length measurement (e.g. length), press the
measure key
again to take the second length measurement (e.g. width). the area is
displayed immediately on the lcD.
Volume measurement
1. Press the mode key
to choose the volume measurement mode; the mode icon
will
blink on the lcD screen.
2. Press the measure key
to turn on the laser beam; position the tool to aim the laser dot at
the target to which you want to measure.
3. Press the measure key
to take the first length measurement (e.g. length), press the
measure key
to take the second length measurement (e.g. width), press the measure key
to take the third length measurement (e.g. height). the volume is displayed immediately on
the lcD.
Single pythagorean theorem measurement mode
the Pythagorean theorem measurement mode is used to measure distances that cannot be
measured directly because an obstacle would obstruct the laser beam or because no target
surface is available as a reflector. correct results are achieved only when the laser beam and
the distance to be determined form a precise right angle (90°).
in the illustrated example (see fig 3), the
length Bc is the unknown distance to be
determined.
For this purpose, aB and ac must be
measured. the lines labeled ac and Bc must
form a right angle.
1. Press the mode key
to choose
the single Pythagorean theorem
measurement mode. the mode icon
will blink on the lcD.
2. Press the measure key
to turn on the laser beam; position the tool to aim the laser at the
target B.
3. Press the measure key
to display the measured length of aB in the first row of the
screen.
4. Without changing the location of the measuring reference point on the tool in position a, aim
the laser dot perpendicularly at the target c.
5. Press the measure key
again to display the calculated length of Bc in the lowest row of
the screen; the distance ac will be displayed at the same time in the second row.
NOTE:
• the distance ac must be shorter than the hypotenuse aB; otherwise the lcD will display “Err
008” to remind you to re-measure the distance ac.
• When taking the two measurements, make sure that they are taken from the same starting
point (a) and that the second measurement is perpendicular to the target c. taking the
measurements correctly will result in the most accurate calculated distance.
