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: Digital protractor troubleshooting
1. The screen does not display or the display is blurred, the possible causes are: the battery is not properly installed or the voltage is too low. Solution: Reinstall the battery or replace it with a new one.
2. the screen measurement value display abnormal may appear due to: rapid shaking caused by the digital protractor's internal response is not timely. Solution: Enter calibration mode and reinstall.
