Definition
标尺 is a technical noun with two distinct senses. In surveying, it refers to a graduated rod used with a level to measure elevation differences. On firearms, it means the rear sight, used for aiming and distance adjustment. The literal meaning 'marked ruler' gives a clue, but the specific uses must be learned separately.
