Single pythagorean theorem measurement mode
The Pythagorean Theorem measurement mode is used to measure distances that cannot be
measured directly because an obstacle would obstruct the laser beam or because no target
surface is available as a reflector. Correct results are achieved only when the laser beam and
the distance to be determined form a precise right angle (90°).
In the illustrated example (see fig 3), the
length BC is the unknown distance to be
determined.
For this purpose, AB and AC must be
measured. The lines labeled AC and BC must
form a right angle.
1. Press the mode key to choose
the single Pythagorean Theorem
measurement mode. The mode icon
will blink on the LCD.
2. Press the measure key to turn on the laser beam; position the tool to aim the laser at the
target B.
3. Press the measure key to display the measured length of AB in the first row of the
screen.
4. Without changing the location of the measuring reference point on the tool in position A, aim
the laser dot perpendicularly at the target C.
5. Press the measure key again to display the calculated length of BC in the lowest row of
the screen; the distance AC will be displayed at the same time in the second row.
NOTE:
• The distance AC must be shorter than the hypotenuse AB; otherwise the LCD will display “Err
008” to remind you to re-measure the distance AC.
• When taking the two measurements, make sure that they are taken from the same starting
point (A) and that the second measurement is perpendicular to the target C. Taking the
measurements correctly will result in the most accurate calculated distance.

Double pythagorean theorem measurement
Use the double Pythagorean measurement mode when one end of the length to be measured
indirectly is higher than the measurement position and the other end of that length is lower
than the measurement position.
In the illustrated example (see fig 4), the
length BC is to be determined, and A is the
measurement position. For this purpose, AB,
AO and AC must be measured. AO and BC
must form right angles.
1. Press the mode key to choose
the double Pythagorean Theorem
measurement mode. The mode icon
will blink on the LCD screen.
2. Press the measure key to turn on the
laser beam; position the tool to aim the
laser at the target B.

4. Without changing the measuring reference point location of the tool in position A, aim the
laser beam perpendicularly at the target O.
5. Press the measure key to display the measured length of AO in the second row of the
screen.
6. Without changing the measuring reference point location of the tool in position A, aim the
laser beam at the target C.
7. Press the measure key again to display the indirect length of BC in the lowest row of the
screen; the distance AC will be displayed at the same time in the third row.
Continuous measurement (locating)
The continuous measurement function (locating) is used for transferring measurements, e.g., from
construction plans. In the continuous measurement mode, the laser distance finder/measuring tool
can be moved relative to the target, during which time the measured value is updated approximately
every 0.5 seconds in the display. For example, the user can measure the distance from the tool to
a wall and then move away from that wall while the actual distance is continuously updated and
displayed, informing the user when the correct distance has been reached.
1. Press the mode key to choose the single-distance measurement mode. If in another
mode, press the clear key to go back to the single-distance measurement mode.
2. Press the measure key and hold it for about 3 seconds to activate the continuous
measurement mode.
3. Move the tool until the required distance value is indicated at the bottom of the display.
4. Press any key to interrupt the continuous measurement. The current measured value is
indicated in the lowest row of the screen. The minimum and maximum values will be displayed
in the first and second row of the screen.
5. Press the measure key again to start a new continuous measuring sequence.
Minimum/Maximum measurement
This function allows the user to measure the minimum or maximum distance measured from a
fixed measuring point. It is commonly used to measure diagonal distances (maximum values),
horizontal distances, or vertical distance (minimum values).
The resulting value can be transferred to area, volume,Pythagorean Theorem measurement and
single-distance measurement modes.
Min/Max function can help eliminate the measuring deviation caused by holding the tool
incorrectly when aiming at the target. It can help to get an accurate calculation of area, volume
and indirect length.
1. Press the mode key to choose among area, volume or Pythagorean Theorem
measurement modes.
2. Press the min/max key to activate the min/max function.
3. Press the measure key to turn on the laser, aim the laser beam at the target you want to
measure and press it again to start the minimum or maximum measuring.
4. Slowly sweep the laser left and right or up and down over the desired target point.
5. Press any key to interrupt the min/max measuring; the minimum or maximum value will be
displayed on the related row of the screen as an accurate length for calculation.
