The invention discloses a multifunctional simple oscilloscope, which comprises a microprocessor, a touch screen, an oscillographic measuring circuit, and a voltage / current measuring circuit. When a working mode of the oscillographic measuring circuit is selected on the touch screen, the measured information is inputted to the microprocessor by the oscillographic measuring circuit, is processed by the microprocessor, and is inputted to the touch screen, and results are displayed on the touch screen. When a working mode of the voltage / current measuring circuit is selected on the touch screen, the measured information is inputted to the microprocessor by the voltage / current measuring circuit, is processed by the microprocessor, and is inputted to the touch screen, and results are displayed on the touch screen. The multifunctional simple oscilloscope has the advantages that the function of a multimeter and the function of the oscilloscope are realized; and since the multifunctional simple oscilloscope mainly consists of the microprocessor, the touch screen and some peripheral components, the number of the components is little, the cost is relatively low, and multiple functions are realized.
Description
technical field [0001] The invention relates to an improvement of a multimeter, in particular to a multifunctional simple oscilloscope which not only has the function of an ordinary multimeter, but also adds an oscilloscope function. Background technique [0002] Among the existing electrical measuring instruments, multimeters are cheap but have few functions, and professional measuring instruments are powerful but expensive; and ordinary multimeters do not have oscilloscope functions, and there are fewer measuring instruments with touch screens, which cannot meet the needs of people's growing Therefore, there is an urgent need to develop a multi-functional simple oscilloscope that is cheap, has both the functions of an ordinary multimeter and adds an oscilloscope function. Contents of the invention [0003] The object of the present invention is to provide a multi-functional simple oscilloscope which not only has the function of a common multimeter but also adds an oscill...
