Tips for Pythagorean Measurement
All Pythagoras measurement can be
applied to different directions of applications ,
only to ensure that the right-angle side is
perpendicular to the measured object.
Note: According to the Pythagorean
Theorem, the right-angle side cannot be
greater than the hypotenuse; otherwise
there is a calculation error.

0.1° is caused by temperature, D is +/- 0~45°, eg: at normal
temperature the accuracy is +/-0.3° at angle of 0°，at
abnormal temperature the accuracy is +/-0.85° at angle of 45° .
1. Measuring Range
The Rear is the default reference. The maximum range shall
be different according to different models. The actual range
refers to the package.
Measuring Accuracy (“D” is the measured length)2.
If measuring under favorable conditions, such as smooth
surface, proper temperature and indoor lighting, the device
is able to work within certain range as indicated.
Maximum deviation occurs under unfavorable conditions
such as bright sunlight or when measuring to poorly reflecting
or very rough surfaces.
Tips: In case of bright sunlight and bad reflection of the object,
please use the target plate or reflector.
3. Wheel Measurement Accuracy
Note: Please keep the device moving smoothly while
