1. Switch the meter off.
2. Press and hold the "SEL/HOLD" button.
3. Switch the meter on and release the button once it starts beeping.
If done successfully, it should beep 5 times. It will then also beep twice every 15 minutes - once to give a warning as usual, then again after 1 minute (this is when it would normally power off, but instead it beeps). Really annoying but whatever. Maybe that's why this function is not documented...?

It is documented.

Indeed! I was convinced I'd read somewhere that the auto power-off cannot be disabled, but I guess that was regarding the shabby DT9205 which I also own. I would have checked the manual, but as it appears I've lost it

Has anyone else experienced a similar issue? When I switch to measuring in mV, it starts to rise to 99 mV (in 10 to 15 seconds) and throws an OL error because the maximum is 99 mV. When I short probes, it returns to 0 mV and measures the voltage perfectly. It doesn't matter if probes are inserted into it or without them, it only returns to 0mV when short probes.
What could be the issue since everything works fine with my other multimeters?

That's completely normal in mV range.

Hi, 2 questions
Can we access readings in UART?
Can it be powered from li-ion battery 10440, ie 3.7v and a dummy cell?
