Need some help on Blue ESR meter assembly

[SmallWalrus]

Hi all,

Sorry in advance for my extremely noob-cake questions

I got myself a Blue ESR meter lately, and got a bit stumped with the final bit of its assembly.

To make it easier for you guys to see what I mean, here is how it looks like now:


I managed to figure out where the two variable pots go as well as the 2 blue LED lights, however what got me are 3 little capacitors. The ones that are 22uF, 33nF and 0.47uF.

There are two 22uF capacitors on the schematic, and the bigger one I have soldered on, but the smaller one seems a bit too big for the big rectangle there. Have I gotten them mixed up?  Also, which of the leads is for the positive terminal? (The positive sign is printed in the middle in between the two leads).

I also can't seem to figure out the remaining two capacitors. The little green blocky one has the code "K63 1817 F1103" which I can't seem to plug into any online calculator at all, while the other smaller brown one has "16L 3333" printed on it, which gave me the same problem.

Isn't it supposed to be a 3 letter code? How are these codes supposed to be interpreted?

The pcb footprint that says "22uF BP" probably means "Bi Polar"
If that's correct then it's a bipolar electrolytic, so doesn't matter which way around it goes.
That also may explain why the + is in the middle.

Check the capacitors you have, if any are bipolar electrolytic they will be marked as such or will be missing the typical negative signs down the side.

Going by size and other people's pictures of their meter, the 0.47uF should be the green block, and the 33nF the smaller one.
