When reading a scale, position your eye perpendicular to the scale’s markings to avoid parallax error. This ensures accurate measurement by aligning your line of sight directly with the scale’s markings.
To read a scale accurately, position your eye perpendicular to the scale’s surface. This means looking straight on, rather than from an angle, to avoid parallax error. Parallax occurs when the position of your eye relative to the scale causes misalignment between the scale markings and the measurement pointer or line. By aligning your eye perpendicularly to the scale, you ensure that your line of sight is directly in line with the markings, resulting in a precise reading. This method helps to eliminate visual distortion and provides an accurate measurement, essential for tasks requiring exactness.
