    2 Quick start instructions 2.1 Power Press and hold the power button on/off. When the battery is dead, use the USB cable to connect to the 5V adapter for charging, and the charging current is about 700mA. It is best to use a computer or mobile phone for charging.

    multimeter function table, select the function and press the [OK] key. If you want to measure the current, insert the red pen into the current hole, and pay attention to the "series" of the meter pen and the power line. When charging: Multimeter is not supported, and the oscilloscope cannot measure high voltage or non-isolated circuits.

    first switch the probe to the 10X position before connecting the high voltage signal, otherwise the high voltage may break down the internal circuit of the oscilloscope. 3.4.3 High bandwidth Because the 1X probe has a large input capacitance, the bandwidth of the probe 1X is usually within 5MHz, so please use the 10X position when the measured signal bandwidth is greater than 5M.
  • Page 9: Horizontal System

    5 Horizontal system 5.1 Time base The time base refers to the time represented by each grid in the horizontal direction on the oscilloscope screen. There are 12 grids in the horizontal direction of the oscilloscope. The sampling time that can be observed on the screen = " time base" * 12.The user can estimate the signal period by observing how many grids a waveform period occupies.

    meets the pre-set conditions. This action of capturing the waveform according to the conditions is the trigger. What does trigger do? 1. Trigger can stabilize the waveform on the screen. 2. Capture the segment of the waveform you want to observe. The trigger supported by the oscilloscope is edge trigger, including rising edge trigger and falling edge trigger.

    dashed lines. The vertical (voltage) cursor can only measure one channel, and whichever channel has the highest priority, measure the voltage of which channel. 8 Menu introduction 8.1 Channel The channel menu includes two options, "Coupling" and "Probe". The coupling can be set "DC coupling" and "AC coupling". DC coupling passes the signal directly.
  • Page 14 For “Normal” mode, The oscilloscope will not refresh the display until there is a waveform trigger. Therefore, in this mode, the screen waveform may not refresh or there is no waveform. It is suitable for measuring discontinuous waveforms and requires users to adjust the trigger level in advance. Trigger type includes rising and falling edges.

  • Page 18 Answer: First, set the coupling to "DC", and adjust the probe to the 10X position (the oscilloscope menu should also be set to the same 10X as the probe). Connect the probe to the power output terminal, and then click the [Auto] key. Pay attention to the "Mean"...
