laser distance measuring device BD8M
4. Briefly press the
ON/MEAS
button (
10
) again to carry out
the third measurement (e.g. height).
ð
The third measured value is displayed in the "Indication
of measured value 2" (
19
).
ð
Upon pressing the
ON/MEAS
button (
10
) for the third time
the device independently calculates the volume and
displays this value in the lower measured value
indication (
20
).

Indirect height measurement (Pythagoras)
Using this method the length of an unknown straight-line
segment (a) can be determined via the Pythagorean Theorem.
This method is suitable for e.g. height measurements.
The measurement result (a) is calculated by determining the
distances b and c.

1. Repeatedly press the button (
11
) until the
symbol for
the indirect measurement appears on the display.

The upper bar (hypotenuse) flashes.
2. First, aim the device at the highest point (A) and briefly
press the
ON/MEAS
button (
10
) once to perform a
measurement. Make sure to hold the device as steady as
possible and place it level on the ground with the two rear
edges.
The position at the two rear edges must not be
changed during the measurements!
ð
The length of the line segment is displayed in the
"Indication of the measured value 1" (
18
).
3. Align the device horizontally at the lower measuring
point (B) and briefly press the
ON/MEAS
button (
10
) once to
measure the horizontal distance.
ð
The second measured value is displayed in the
"Indication of measured value 2" (
19
).
ð
The line segment to be determined is displayed as
result in the lower measurement value display (
20
).
Twofold indirect height measurement
This method is suitable for e.g. height measurements when you
are not at the same height as the base point.
The measurement result (a) is calculated by determining the
distances b, c and d.

symbol for
the twofold indirect measurement appears on the display.
2. First, aim the device at the highest point (A) and briefly
press the
ON/MEAS
button (
10
) once to perform a
measurement. In doing so, hold the device as steady as
possible.
The alignment of the device in relation to the
reference point must not be changed during the
measurements!
ð
The length of the line segment is displayed in the
"Indication of the measured value 1" (
18
).
3. Align the device horizontally (at measuring point (B)) and
briefly press the
ON/MEAS
button (
10
) once to measure the
horizontal distance.
ð
The second measured value is displayed in the
"Indication of measured value 2" (
19
).
4. Aim the device at the deepest point (C) and briefly press
the
ON/MEAS
button (
10
) once to perform a measurement.
ð
The third measured value is displayed in the "Indication
of measured value 2" (
19
).
ð
The line segment to be determined is displayed as result in
the lower measurement value display (
20
).
