Measuring
When the parameters are set up and the cut-off samples length is decided, it will come to measurement. Point the Stylus mark to the measured area stably and then press the Start Key on the top to start measurement, liquid crystal display as "Waiting". At this time, it will be invalid to press the start button.
After the "Waiting" disappeared with two "didi" sound, the measurement has being finished, and the screen will show the measured value.
