Q1: What is a digital protractor?
A1: The digital protractor is a device for measuring small angles, which can be used to measure tilt for horizontal position, parallelism, and perpendicularity of two parts, straightness of machine tools and instrument guides, table flatness, and flatness of flat plates, etc.
Q2: How does the digital protractor work?
A2: When the axis in the digital protractor base is rotated in one direction, the count increases, and when the direction of rotation is changed, the count decreases. The count is related to the initial position of the goniometer. When the goniometer is initialized, its count is set to 0. By calculating the angle of rotation, the position and speed can be easily measured.
Q3: What is the accuracy of the digital protractor?
A3: Digital Protractor measure an angle over 360 degrees with a high accuracy of 0.1 degrees.
Tips: What is the repeatability of a digital protractor?
Under the same measurement conditions for the four positions of the inclinometer 0 °, 90 °, 180 °, and 360 °, respectively, five readings, the difference between the maximum and minimum reading of each position for the position of the indicated value repeatability. The repeatability of the digital protractor is determined by the maximum value of the repeatability of the scale in the four positions.
