Abstract

A method for scale adjustment of touch-based measurement equipment has steps of providing a touch-based screen with a waveform area; determining if a first-direction gesture or a second-direction gesture is present on the waveform area; when the first-direction gesture is present, determining if an object touches one of two portions of the waveform area divided along a second direction of the waveform area and incrementing or decrementing a first scale when positive; and when the second-direction gesture is present, determining if an object touches one of two portions of the waveform area divided along a first direction of the waveform area and incrementing or decrementing a second scale. Scale adjustment on touch-based measurement equipment using one finger can be implemented with the foregoing method.
