NTT: Hioki 3490 Analogue MΩ HiTESTER

What’s that, analogue you say? Analogue??! Surely in this world of digital test instruments there’s simply no value to something with a pointy pointer that points to printed pictures of poxy numbers?! Well, maybe… but surely all those pesky Australians can’t be wrong?!

Notes:
At 5:51 I wibble on about aligning the needle through the centre of the infinity marks on the display, then after much twiddling I leave it cock-off. That’s just because the camera was in the way and I was looking at it from the side, but it goes to show how an adjustment of this sort needs to be made when facing it squarely on.

It’s also of note that I say the MFT1552 shows an electronic ‘analogue’ display ranging in voltage from 0 to 600, the latter number indicating full-scale deflection, yet the legend printed to the left of the Megger’s LCD shows no more than 500V should be applied… so that’s a bit weird and serves to make me look quite the fool.

I should also state that Megger, and the 15 or 17 series of testers, aren’t the only brand or models of digital instruments that show an analogue representation on their LCD displays. My TIS MFT Pro has such on IR, in a very basic way, and that cute Robin KTS1625 has a digitally represented scale too. Other machines have similar no doubt.

Oh, I know there's been a glut of new videos spouted out here over the past week which is most out of character. Rest assured, the next one may be weeks away!
