direct measurement. Single intermediate distances should be measured as
accurately as possible, this will result in a small error in the intermediate
measurement result.
Indirect measurement - Pythagorean Theorem (V)
Switch on the device and press the button marked FUNC/UNITS to select
area measurement marked with a right triangle symbol. The display shows
the measurement symbol with a fl ashing edge, the length of which will be
measured. Perform the measurement as in the case of measurement of
a single distance, and then measure the second distance. The distance
measured can be viewed in the previous measurement fi eld, and the dis-
tance calculated using the Pythagorean Theorem is displayed in the last
measurement fi eld. CAUTION! The fi rst distance measured must be greater
than the second one. Otherwise, the result of measurement will be invalid.
Indirect measurement - Dual Pythagorean Theorem (VI)
This type of measurement is used, when the beginning and end of a dis-
tance is located above or below the point of measurement. CAUTION! The
most accurate results of measurement are obtained, when the point of
measurement is located in the middle of the measured distance. Switch on
the device and press the button marked FUNC/UNITS to select area meas-
urement marked with a double right triangle symbol. The display shows
the measurement symbol with a fl ashing edge, the length of which will be
measured. Perform the measurement as in the measurement of a single
distance, and then measure the second distance. The distance measured
can be viewed in the previous measurement fi eld, and the distance calcu-
lated using the Pythagorean Theorem is displayed in the last measurement
fi eld. CAUTION! The fi rst and the third distance measured must be greater
than the second one. Otherwise, the result of measurement will be invalid.
Adding and subtracting the distance
The laser distance meter enables adding and subtracting of measurements.
Switch on the device and perform measurement of the fi rst distance. Press
once the button marked +/- to add distances or twice to subtract. The dis-
play will show the symbol of the mathematical operation. Then measure
the second distance directly. The result of the operation appears in the last
measurement fi eld. Pressing the adding or subtracting button again allows
you to take another distance measurement and add or subtract it from the
previous result.
Measurement memory
The distance meter is equipped with a memory which automatically stores
the last 10 measurements. Older results are deleted and automatically
erased and replaced with new ones. To view the stored results, switch on
the device and press the button marked FUNC/UNITS until the memory
bank number appears. By pressing the +/- button you can view the values
stored in successive memory banks.
