Dear Sir,You can replace a 4M crystal oscillator.
Test again for 1,2 in the figure below. 1 is DC voltage, 2 is AC voltage, see if this transformer has 3.5V.

I checked the crystal and it is definitely not operating correctly. Attached is an image of measuring it with another scope. I also couldn't detect any voltage across C46.

I have the same issue. Attached is a picture of the display. The Scope and AWG functions work fine. It is just the DMM has no value displayed, even 0. I have updated the firmware and the problem persists. I am willing to replace components if it is a hardware issue. I could not find any user replaceable fuses.

Is the measurement data of the multimeter not displayed? Don't all the gears of the multimeter show? If there are other problems, please provide relevant videos for our better reference.
