Indirect measurement using dual right-angled triangle (VI)
The measurement is made in case the beginning and the end of a distance is above and below the point of measure-
ment.
NOTE! The most accurate measurement results are obtained when the measurement point is in the middle of a dis-
tance measured. Any other placement of a measurement point will result in measurement error.
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 dual 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 and third 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 and third distance measured must be bigger than the second one. Otherwise the measurement result is
wrong.
Indirect measurement using divided right-angled triangle (VII)
The measurement is made in case the beginning and the end of a distance is above or below the point of measure-
ment.
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 dual 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 and third distance.
The measurement of a distance will be shown in the field of previous measurement, and the distance calculated in the
field of result of last measurement.
NOTE! First distance measured must be bigger than the second one, and the second one bigger than the third one.
Otherwise the measurement result is wrong.
Indirect measurement using the hypotenuse (VIII)
The measurement applies when the beginning of a distance is just in front of the range-finder and the end of a distance
over or beyond the beginning of a distance. Place the range-finder horizontally, angle marker should indicate „0.0 ",
O
and the laser spot indicates the beginning of a distance measured. Then lift or lower the range-finder and make the
measurement. The display will show distances of all three sides of a right-angled triangle generated during the meas-
urement, and value of an angle between cathetus and horizontal hypotenuse.
Indirect measurement using two hypotenuses (IX)
The measurements applies when the centre of a distance measured lies directly opposite the range-finder, one of the
ends is over, and the second one below the centre. Place the range-finder horizontally, angle marker should indicate
„0.0 ", and the laser spot indicates the centre of a distance measured. Lift the range-finder and make the measurement,
O
than lower the range-finder by the same angle as lifted and make the measurement. The display will show both dis-
tances measured, an angle between them and the distance between the beginning and the end of the measurement.
Note! If the centre of a section measured shall not lie directly opposite the range-finder in horizontal position, then the
result shall be erroneous.
Adding and subtracting distances
The range-finder allows adding or subtracting the measurements. Start the device, make direct measurement of the
first distance, and then press the button "sum / difference" of distances, briefly, to add distances, or extendedly, to
subtract distances. Depending on the selection the display will show "+" symbol for adding distances or "-" symbol for
subtracting distances. Then make direct measurement of the second distance. The result will be displayed in the field
of last measurement. Pressing again the adding or subtracting button will allow making subsequent measurement of
distance and adding to or subtracting from the previous result.
