The video is interesting for dealing with some meter errors but poorly explained and presented by its OP and difficult to see smaller detail clearly, on the rather distant meters. It doesn't appear to have the same symptoms as the Current Test on the SKLEP
The 3430 only uses 'OL' on certain ranges (as mentioned in my earlier post #9618) plus Diode check, but it doesn't appear to include Current
I don't know the context of the other photo, two posts above, but again it doesn't appear to contain the same symptoms as the SKLEP demo Current Test
I find it interesting that, despite the incongruous appearance of the '1' in the LH segment of the m.s. digit place, the demo meter shows the digital and the 'analogue' readings to be in agreement both about the '457.3' part and the negative polarity (again mentioned in that same earlier post)
Still, we're promised further excitement with repeats of the Current Test ahead, so maybe we'll learn more later!
