triangle. All measurements need to be to points on a single straight
line.
Using Two Points

1. Press
Indirect Measurement Button
once. The symbol
will show in the display. The distance to be measured will flash
in the symbol.
2. Press
ON/Measurement Button
to turn ON the laser, aim
the laser at the upper point (1) and trigger the measurement.
The measurement will be displayed in the first line.
3. The next distance to be measured will flash.
4. Press
ON/Measurement Button
to turn on the laser, keep-
ing the instrument as perpendicular to the line between the
measurements as possible, Press
ON/Measurement Button
again to measure the distance result of the horizontal
point (2). The measurement will be displayed in the second
line.
5. The result of the calculation is displayed in third line.
Volume Measurement
1. Press
Area/Volume button
. The symbol appears in the
display. The distance to be measured will flash in the symbol.
2. Press
Area/Volume button
again, the symbol for vol-
ume measurement appears in the display. The distance to be
measured will flash in the symbol
3. Press
ON/Measurement Button
to take the first measure-
ment (e.g. length).
4. Press
ON/Measurement Button
again, to take the second
measurement (e.g. width).
5. The result of the area calculation is displayed in the third line;
the individually measured values are displayed in lines 1 and 2.
6. Press
ON/Measurement Button
again, take the third dis-
tance measurement (e.g. height). The value is displayed in
the second line.
The result of the volume calculation is displayed in the third line.
Indirect Measurements
Indirect measurements are used when a direct measurement is not
possible. Indirect measurements are calculated from measurements
of the hypotenuse and one side of a right triangle (triangle with a 90
degree angle). For instance, if calculating the height of a wall from the
ground, measurements would be taken to the top of the wall (hypo-
tenuse), and perpendicular to the line between the two measurement
points at the wall base (side). From these two measurements, the
distance between the two measurement points is calculated.
Indirect measurements are less accurate than direct measurements.
For greatest accuracy with Indirect Measurements, hold the micro
LM-100 in the same position (only changing angle) for all measure-
ments. Make sure that the laser beam is perpendicular to the line be-
tween the measurement points when measuring the side of the
