UNI-T UT61D genuine bodge diode
(1/1)
hozone:
Hello,

I've a UT61D with some AC reading problem, reading are lower then it should be. As example my main here in Italy it's something around 220V but this the meter reads 50V.
Opening it I've seen a few components with some sign of corrosion, at least it seems to me that. So simply resoldering three components solves the problem. For this reason I think my problem should have been a cracked solder.
But that's not the reason for this post.
Here I just want to show you what I think it was a genuine bodge high speed switching diode.
When I opened the multimeter, I've noticed that the R9 does not seems a resistor. Indeed desoldering it, turns out that over the resistor someone in the farm soldered a high speed switching diode. It's marked C3, and I think it's a 1SS226, maybe to protect something, but I've not investigated further.
This is just to show you some image of the meter and that diode.

~ Side note: Image taken before desoldering and soldering it back again ~
~ Side note: date on picture is wrong, I've take those picture a few days ago... not 2018 ~
