7. Indirect Pythagoras Measurement ①
1) Press the
button to switch to the indirect Pythagoras
measurement ①
.
2) According to the flashing edge, point the laser at the first
point of the target, and press the
kbutton to measure
the first hypotenuse.
3) Rotate to the direction perpendicular to the target with
the set reference as center, and press the
measure one right-angle side.
4) Rotate to the third point of the target with the same
reference as center, and press the
the second hypotenuse.
5) The calculation result of the length between the first point
and the third point is displayed at the bottom of the screen.

1. Range
The range data is based on the rear reference (default); the maximum range may vary
depending on the model version, and the actual range is shown on the product packaging.
2. Accuracy ("D" represents the measured length)
Under good measurement conditions (good measurement surface/room temperature/
indoor lighting, etc.): up to the rated range.
Under poor measurement conditions (too much light, weak reflection on the surface of
the measured object or large temperature difference, etc.): the error may increase.
Tip: Use a reflector or a good reflective surface in the case of poor daylight or target
reflection.
3. In the ideal state, the short distance accuracy can be up to 1mm
(Ideal state refers to constant speed (speed < 1m/s) and flat contact surface; short
distance means <1.5m)
4. Angle Error
0.1° is the error caused by the temperature, D is +/-0~45°.
For example, the 0 degree error is +/-0.3° at room temperature, the 45 degrees error is
+/-0.85° at non-room temperature.
