Open Calibration and select a reference object (credit card, A4 paper, or coin).
Place the physical object flat against your screen, then adjust the slider until the on-screen box matches its real size.
Choose Caliper mode and drag the red handles to span the object you want to measure.
Read the measurement in cm, inches, and pixels simultaneously.
用信用卡校正後,在多數螢幕上準確度通常在 1-2mm 以內。關鍵是使用校正滑桿,將螢幕上的矩形與實體參考物仔細對齊。
切換至游標模式,拖曳垂直線上的紅色三角把手,兩者之間的距離會即時更新。你也可以在測量區域任意點按,將最近的把手吸附到該位置。
