This allows, for example, determining a distance to be travelled while approaching or drifting away from the surface
measured.
Start the device, press and hold down for approx. 2 seconds the switch/continuous measurement button. The device
shall be switched to continuous measurement mode. This will be indicated by “MIN” and “MAX” symbols on a display.
Displace the range-finder while reading indications on a display. The range-finder automatically saves the minimum and
maximum distance measured and shows them on a display.
NOTE! Range-finder displacements that are too fast may result in erroneous indication. If “Error” message is shown on
a display, reduce the speed of range-finder displacement. In order to go back to single measurement mode, press the
switch / continuous measurement button.
Area measurement (III)
NOTE! It is possible to measure the area of only one rectangle at a time. Areas of other shape should be split into
rectangles, and then make the measurement of each one separately and then make the total.
Start the device and by pressing the measurement base button select the point from which the distance is to be meas-
ured. By pressing “Menu” button select the area measurement marked with a symbol of a rectangle. The display will
show a symbol of measurement with pulsating edge, length of which is to be measured. Make the measurement as in
the case of single measurement, and then measure the second distance. The measurement of a distance will be shown
in the field of previous measurement, and area calculated shall be shown in the field of last measurement.
Pressing a switch for a short time deletes a distance previously measured , by pressing the switch again you may delete
the previously measured distance.
Measurement of cubic capacity (IV)
NOTE! It is possible to measure the area of only one cuboid at a time. Cubature of other shape should be split into
cuboids, and then make the measurement of each one separately and then make the total.
Start the device and by pressing the measurement data base button select the point from which the distance is to be
measured. By pressing “Menu” button select the area measurement marked with a symbol of a cuboid. The display will
show a symbol of measurement with pulsating edge, length of which is to be measured. Make the measurement as
in the case of single measurement, and then measure the second and third distance. The measurement of a distance
will be shown in the field of previous measurement, and the cubic capacity calculated shall be shown in the field of
last measurement.
Pressing a switch for a short time deletes a distance previously measured, by pressing the switch again you may delete
the previously measured distance.
Indirect measurement
Measurement applies to measuring distance in the case when direct measurement is not possible, for example there
are obstacles on the path of a laser beam. Measurement may be used to measure the height, when the surface
measured is not directly accessible. Due to the fact, that the result of measurement depends on calculations based on
distances measured indirectly, the result of such measurement will be always prone to bigger error than direct measure-
ment. It is required to thoroughly make the measurements of single indirect distances, this will result in small error of
indirect measurement. In case of indirect measurements it is recommended to place the range-finder on a tripod and
set the base of measurement in the axis of tripod hole.
Indirect measurement using right-angled triangle (V)
Start the device and by pressing the measurement base button select the point from which the distance is to be
measured. By pressing “Menu” button select the area measurement marked with a symbol of right-angled triangle. The
display will show a symbol of measurement with pulsating edge, length of which is to be measured. Make the measure-
ment as in the case of single measurement, and then measure the second distance. The measurement of a distance
will be shown in the field of previous measurement, and the distance calculated using Pythagoras formula shall be
shown in the field of last measurement.
NOTE! First distance measured must be bigger than the second one. Otherwise the measurement result is wrong.
