Volume Measurement
For volume measurements, push button 5
until the indicator for volume measurement
appears in the display.
Afterwards, measure the
length, width and the
height, one after another,
in the same manner as
for a length measurement.
The laser beam remains
switched on between all three measurements.
After taking the third measurement, the volume
is automatically calculated and displayed. The
last individual measured value is indicated at
the bottom in the display, while the final result
is shown at the top.
Values exceeding 99990 ft 3 cannot be
displayed; “Err.” is indicated in the display. In
this case, switch the unit of measure to meters
(see “Changing the Unit of Measure”, page 9).
Area or Volume
Rounding of Large Calculations
For values larger than 9999 feet or meters the
rangefinder rounds the calculated value to the
nearest 10 feet or 10 meters. Accuracy in such
situations is always 99.95% or better.
Continuous Measurement (Tracking)
(see figure E)
The continuous measurement mode (tracking)
is used for the transferring of measurements,
e.g., from construction plans. In continuous
measurement mode, the rangefinder can be
moved relative to the target, whereby the
measured value is updated approx. every 0.5
seconds. As an example, the user can move
from a wall to “walk off” the required distance,
while the actual distance can be read
continuously.
For continuous measurement, push button 4
until the indication “Con.” appears in the
display.
Press the measuring
button
9 to initiate the
measuring procedure.
Move the rangefinder until
the required distance
value is indicated at the
bottom of the display.
Pushing the measuring button 9 interrupts the
continuous measurement. The current
measured value is indicated in the display.
Repeated pushing of the measuring button 9
starts the continuous measuring again.
The continuous measuring automatically
switches off after 5 minutes. The last
measured value remains indicated in the
display. The continuous measuring can also be
ended by pushing button
4 or 5, which
changes the measuring mode.
Indirect Length Measurement (see figure F)
The indirect length measurement is used to
measure distances that cannot be measured
directly because an obstacle would obstruct
the laser beam or no target surface is available
as a reflector. (The DLR165 use pythagorean
theorem, a2+b2=c2 to achieve this). Correct
results are achieved only when the laser beam
and the sought distance form an exact right
(90°) angle.
In the illustrated example, the length C is to be
determined. For this purpose, A and B must be
measured. A and C must form a right angle.
For indirect length measurements, push button
5 until the indicator for indirect length
measurement appears in the display.
Measure the distance
A
as for a length
measurement. Pay
attention that the line
segment
A and the
sought distance C form a
right angle. Afterwards, measure the distance
B. The laser beam remains switched on
between both measurements.
Pay attention that the reference point of the
measurement (e.g., the rear edge of the
rangefinder) is at the exact same location for
both measurements.
After completing the second measurement, the
distance
C is calculated automatically. The last
individual measured value is indicated at the
bottom in the display, while the final result
C is
indicated at the top in decimal feet or meters.
Deleting Measured Values
Pushing the clear button 1 deletes the last
individual measuring value determined in all
measuring modes. Pushing the button
repeatedly deletes the individual measured
values in reverse order.
MEMORY MODES
When switching off the rangefinder, the value
in the memory is retained.
