Even in garage, with the door open and the sunshine pouring in, you can easily read the display. 【Factors for Inaccuracy】Calibration errors, where the angle finder is not properly calibrated or becomes misaligned, can lead to inaccuracies. Extreme temperatures, high humidity, or nearby magnetic fields can affect the performance of the angle finder. Inaccurate sensors or poor sensor calibration can introduce errors. User errors, such as improper positioning or alignment, can also result in inaccuracies. Additionally, low battery power can lead to inaccurate measurements. 【Angle Finder Laser Using】Laser use can encounter problems like beam divergence, misalignment, power fluctuations, environmental interference, safety hazards, and thermal effects. Solutions include using beam expanders or collimators, aligning the laser properly, stabilizing power supply, maintaining clean surroundings, following safety guidelines, and implementing cooling mechanisms. Consult manufacturer guidelines and seek professional assistance as needed. 【Note Please】If the protractor doesn't work, please check the battery condiction or reset it. Additionally, Levels can be sensitive to changes in temperature, humidity, or exposure to extreme conditions. These factors can impact the materials and mechanisms within the level, causing them to expand, contract, or deteriorate over time. This can result in decreased accuracy or malfunctioning of the level
