TDA1541AS2:
Ok, thank you.
That makes sense :-+

Not AI bot. (Whatever that is in this warped world)
I'm an electronics engineer with audio interest.
I'm asking the above (re: duty cycle measurements) as I had a cheapo dmm that had the duty cycle available in the normal volts range and able to take the measurement at 240vac levels.
But I guess I wouldn't be able to it with the BM789. (OR can I?)
Not willing to damage my meter or test it without a good understanding.
Also, the Brymen manual has bugger all stated in the specs regarding the operational limits of the mV range.

When you asked the above question, you were not referring to your personal safety but rather the meters ability to withstand it. "... and able to take the measurement at 240vac levels"
From that perspective, I did much worse to this meter than what you are proposing and it held up just fine. That said, let me try it tonight and see if I can get a good measurement.
joeqsmith:
Being a EE myself, I can't think of one time where I wanted to measure the duty cycle of the mains but what ever floats your boat. Both meters in parallel, 60Hz sinewaveish, 240V. Of course, you follow my videos, you would know this isn't going to pose a problem for this particular meter. Even some of the cheapest ones I look at with their lack of a surge resistor and tiny 5mm PTCs would handle this just fine.
Hydrawerk:
It is time for a partial teardown of BM789. One screw is missing, but I do not care.

I've given up all hope of them releasing the Bluetooth version.
