A part of the review has been auto-translated.
Its quality is usable._The reason why it got 2 stars from me is because it doesnt have huge shortcomings._1. The USB is only for charging, not for data connection, in other words, you can forget about the firmware update._2. There is no baxseline zeroing in oscilloscope mode._In other words, the DC offset must be taken into account and corrected by yourself._I bought two devices, one with -900mA and the other with -1.5A negative DC offset._3. What I think is its biggest shortcoming is that it does not have Single and normal triggers. And since you cant update the firmware, you can forget about it.__The accuracy of the DC is good, the part of the multimeter is of the usual good quality from Owon._The display is clearly visible, but the surface of the oscilloscope is smaller compared to the HDS120, the height is the same, but the width is almost half._The shortcomings of the HDS120 can also be discovered here.
Perfect, thank you.
