Heyho, sorry for digging out this old thread, but i just bought the U1242B and while checking if i want to buy it, i found this thread over google. I was not sure if i want to buy this multimeter cause of the continuity tester and found out something, which is not mentioned here.
If you look very close, you can see, that the multimeter is autoranging, while doing the continuity test.
However, you can make it way faster, by choosing manual ranging.(something between 50ms and 200ms - just my subjective feeling). You can even speed it up a bit by choosing a higher range.
here a short part of the manual:
measurement range Beeps, when
1000,0 < 10
10,000 k < 100
100,00 k < 1 k
1,0000 M < 10 k
10,000 M < 100 k
100,00 M < 1 M
Maybe i can make a short video, but it will need some days
edit: dedoh, havent looked properly at the video, manual ranging was already selected. Somehow, my multimeter does beep, when i do this scratching.
