Package List: 1 x Colorful Digital Oscilloscope1 x Charging Cable1 x Oscilloscope Probe1 x Probe Hook1 x Senseless Adjustment Bit8 x Color Ring 2 x Probe Hook Cover1 x Oscilloscope Instruction1 x Test Pen Instruction1 x Storage Bag Note: When measuring unknown voltage, the probe handle should be toggled to the 10X gear first to prevent the input voltage from being too high and burning the oscilloscope. And then according to the size of the measured voltage to determine the use of 1X or 10X gear 2.1X probe gear bandwidth of 5MHz, 10X probe gear bandwidth of 100MHz, when measuring higher than 5MHz frequency, you need to dial the probe handle to 10X gear, the oscilloscope also needs to be set to 10X gear, because the oscilloscope probe line there is up to 100‑300pF capacitance, the signal through the Probe to the input of the oscilloscope will be significantly attenuated, the equivalent bandwidth of 5MHz, in order to match the capacitance of the probe line, the input of the probe line will first attenuate 10 times (handle toggle to 10X gear), at this time the capacitance can be used for impedance matching, the bandwidth of 100MHz. note that only 100MHz bandwidth or more probe
