*The working range and accuracy depend on how well the energy of laser is reflected from surface

(mostly comes from scattered light) and the target reflectivity. The brightness of laser point to

ambient light intensity or use a target plate (Kodak White) may helps for increasing the working range and the stability of accuracy.

*In favorable condition, accuracy could be in ±1.5 mm(2δ) and a deviation influence of ±0.25mm/m must be taken into count after ten meters.

*In unfavorable condition, such as bright sunlight, rough surface, very short distance, or a poor and extra strong reflected signal may cause the deviation reach or

over ±10mm and also may bring an ambiguous cycle which may lead the measures to an unexpected result..
