Mark-out Function
For uniform marking of distances, two clear-
ances a and b can be entered and saved. In the
following measurement, the currently measured
distance is compared with the clearance a and
the difference is shown on the display.
– Press button four times. The mark-out
function symbol appears on the display and
measure a flashes.
– Enter measure a with buttons and
save with button .
– Afterwards, enter measure b and save. The
laser beam is activated.
– Align the laser beam and move the device
while watching the display. The arrows on
the display indicate in which direction the
device is to be moved.
– When the acoustic signal changes and
0.000 is indicated, the measuring value at
the rear stop/rest corresponds with meas-
ure a. Mark this point.
– Move the device further towards the measure
a + b and mark the second determined point.
The next measure to be determined is now at
a + b + b etc.
The next measured value is displayed in the bot-
tom intermediate indication.
The function can be ended by pressing the
button. The saved measures a and b are retained.
Indirect Measurement using the
Pythagoras’ Theorem
The device can determine a distance based on
auxiliary measurements in accordance with the
mathematical Pythagoras’ theorem. This is use-
ful when a direct measurement cannot be taken.
❏ The measured points must be in one line.
❏ The measuring sequence shown in figures ➐
➑ ➒ must be adhered to.
❏ Best results are achieved when the device is
turned around a firm point. As an example,
place the device against a wall and turn it
around the completely folded out stop/rest
angle.
❏ Use the tracking function to determine the small-
est distance rectangular to the target and the
greatest distance for the other measurements.
❏ The automatic release/timer can be used.
❏ Values from the memory can be called up.
Pythagoras I – Determining
a Distance with 2 Auxiliary
Measurements
➐
– Press pushbutton until the symbol
appears in the display. The laser is activated.
– Aim at the upper measuring point and initi-
ate measurement 1 by pressing button .
– Hold the unit as horizontal as possible. To initi-
ate continuous measuring, press and hold but-
ton . When the rapid beep sounds, circle
generously around measuring point 2. Press
button to end the measurement.
The auxiliary measurements and result l are
indicated in the display.
Pythagoras II – Determining
a Distance with 3 Auxiliary
Measurements
➑
– Press pushbutton until the symbol
appears in the display. The laser is activated.
– Aim at the upper measuring point and initi-
ate measurement 1 by pressing button .
– Hold the unit as horizontal as possible. To initi-
ate continuous measuring, press and hold but-
ton . When the rapid beep sounds, circle
generously around measuring point 2. Press
button to end the measurement.
– Aim at the bottom measuring point and initi-
ate measurement 3 by pressing button .
The auxiliary measurements and result l are
indicated in the display.
Pythagoras III – Determining a
Partial Distance with 3 Auxiliary
Measurements
➒
– Press pushbutton until the symbol
appears in the display. The laser is activated.
– Aim at the upper measuring point and initi-
ate measurement 1 by pressing button .
– Aim at the center measuring point and initi-
ate measurement 2 by pressing button .
– Hold the unit as horizontal as possible. To ini-
tiate continuous measuring, press and hold
button . When the rapid beep sounds, cir-
cle generously around measuring point 2.
Press button to end the measurement.
