I have a 475K 630V polyester capacitor that's reading 47.28nF shouldn't it be 4700nF (4.7uF)? Any ideas?
Do you got similar problems with other caps too or just with that one?
It's small 4x5x2mm it says 475K 630V on it.

The ESR values of the Rubycon electrolitics (16V, 10uF) are 4.3 and 4.7 Ohms. They're high, but could be normal, according to some ESR charts. I couldn't find any official Rubycon documentation with ESR values.
Anyway, it lacks an ISP header (not a problem) and the 2.5 volt reference. Anything else you notice?
I haven't properly tested yet, I'm a beginner and I don't have many components lying around.
Hi guys. Bought one to these testers and only did a few component tests when it started to display the word "Cell!" every time now.
I made the Markus Frejek's AVR component tester, too.

A connected capacitor can be measured in the range 35pF to 100MF with a resolution of up to 1 pF

Cool 100MegFarad. Will come in handy testing the decoupling caps at Comanche Peak.
Will this "cheapo" ISP programmer be capable of programming the ATMega168P & ATMega328/P MCs ?

It is listed as capable for the ATMega168 (non-P).

It is listed as capable for the ATMega168 (non-P).Yes. Works fine. I have one of those and it's an USBasp clone. Mine came with an old firmware (2007), but as I ordered two, I used one to update the other.
Another question - On my SMD TransistorTester unit I'm trying to replace the ATMega168P (TQFP-32) to its drop-in replacement - the ATMega328P. Found (in Ali-Express) the ATMega328P-AU (10 Pcs for $15). Is the *-AU part OK ?
