Embodiment Construction
[0021] The technical means adopted by the present invention to achieve the intended invention purpose are further described below in conjunction with the drawings and preferred embodiments of the present invention.
[0022] For a preferred embodiment of the present invention, please refer to figure 1 As shown in the flow chart, it includes:
[0023] Provide a touch screen, so that there is a waveform display area on the touch screen (step 101);
[0024] Determine whether a first direction gesture occurs in the waveform display area (step 102); if a first direction gesture does not appear, then determine whether a second direction gesture occurs in the waveform display area (step 103);
[0025] When it is judged that the gesture in the first direction appears in the waveform display area, then it is judged whether there is a click object at the opposite ends of the first direction in the waveform display area (step 104), and if so, a switching of the first measurement gear is...

The invention relates to a gear switching method of a touch-sensitive measuring instrument, which includes: providing a touch-sensitive screen, and making the touch-sensitive screen have a waveform display area; judging whether a first wave appears in the waveform display area; A direction gesture or a second direction gesture, when the first direction gesture appears, then judge whether the waveform display area has a click object at the opposite ends of the first direction, and if so, execute a increment or decrement of the first measurement gear switch; if the gesture in the second direction appears, it is judged whether there is a click object at the opposite ends of the waveform display area in the second direction, and if so, an incremental or decremental switch of the second measurement gear is executed; On the control measuring instrument, one finger can switch gears step by step.
Description
technical field [0001] The invention relates to a gear switching method of a touch-sensitive measuring instrument, in particular to a method capable of realizing single-finger switching of measuring gears segment by segment. Background technique [0002] For example, measuring instruments such as oscilloscopes and spectrum analyzers use the waveform as the display content of the measurement signal. Taking the oscilloscope as an example, the waveform displayed by the oscilloscope has the amplitude of the signal on the vertical axis and the time of the signal on the horizontal axis. The obtained value or signal exceeds the scope of the vertical or horizontal channel of the oscilloscope, and there is often a need to switch the measurement gear, such as 1X, 10X, 100X, and 1000X. The most traditional gear switching method is to use the gear knob to switch. After the touch screen is also used in the above-mentioned measuring instruments, it also supports the use of touch to adjus...
