laser distance measuring device BD21 / BD26
Carrying out single distance measurement
1. Briefly press the Switch-on/measurement button (7) to
activate the laser.
2. Point the laser at the target area.
3. Briefly press the Switch-on/measurement button (7) again
to perform a distance measurement.
ð
The measured value is immediately indicated on the
display.
Adding / subtracting measured values
1. Carry out a single distance measurement.
2. Press the Plus button (17) to add the next measured value
to the previous one.
Press the Minus button (8) to subtract the next measured
value from the previous one.
3. Press the Switch-on/measurement button (7) to determine
the next measured value.
ð
The overall result will be indicated in the lower
measurement value display. The individual measured
values will be indicated in the upper measurement value
displays.
Performing an area measurement
1. Briefly press the Area/room volume button (16) one time.
ð
The symbol
for area measurement appears on the
display.
2. Briefly press the Switch-on/measurement button (7) to
carry out the first measurement (e.g. length).
3. Briefly press the Switch-on/measurement button (7) again
to carry out the second measurement (e.g. width).
ð
Upon pressing the Switch-on/measurement button (7)
for the second time the device independently calculates
the area and displays this value in the lower
measurement value display. The most recently
measured value will be indicated in one of the upper
measurement value displays.
Performing a volume measurement
1. Briefly press the Area/room volume button (16) twice.
ð
The symbol
for volume measurement appears on
the display.
ð
The side to be measured in each case is indicated on
the display by flashing.
2. Briefly press the Switch-on/measurement button (7) to
carry out the first measurement (e.g. length).
3. Briefly press the Switch-on/measurement button (7) again
to carry out the second measurement (e.g. width).
4. Briefly press the Switch-on/measurement button (7) again
to carry out the third measurement (e.g. height).
ð
Upon pressing the Switch-on/measurement button (7) for
the third time the device independently calculates the
volume and displays this value in the lower measurement
value display.
Performing a non-stop / min and max measurement
Use the non-stop measuring function to correlate
measurements e.g. with construction drawings. With this
measurement method the device can be moved closer toward
the target with the measured value being recalculated roughly
every 0.5 seconds. The corresponding maximum and minimum
measured values are displayed in the first and second line
respectively.
For instance, you can direct the laser beam at a wall and then
retreat from it step by step. Keep reading the measured values
until the desired distance is achieved.
1. Press the Switch-on/measurement button (7) for a long
time until an acoustic signal can be heard.
2. With reference to the target point, move the device slowly
back and forth as well as up and down (e.g. in a corner).
3. Briefly press the Switch-on/measurement button (7) to
terminate the non-stop measurement.
ð
The maximum and minimum measured values and the
difference (Δ) between these two are indicated on the
display. Additionally, the last measured value will be
displayed in the bottommost line.
