now i see why w1zz said for me to go all out and put everything i would expect to see in a review.
this psu tester ISNT very accurate. YES it does its job and i do reccomend it to you guys but its not as accurate as SOME people would like to see. when testing side by side with a digital multi meter, i saw up to 0.17v of difference from the ps-224 to the actual voltage reported by the DMM. the DMM i have is a VERY high quality Fluke model that is presumably quite accurate. i would trust it over a $30 psu tester any day. i SHOULD HAVE put that in the review but i didnt. i thought that it may be too much info or too far over some peoples heads and might possibly lead to the confusion that the ps-224 appearing crappy which its not. the ps-224 does its job as intended. if you want advanced readings then get a good DMM and be happy. it wont be as easy to use but it would be more accurate and you could monitor real time voltages while the pc is in use.
i took the ps-224 to a local computer shop that my friend owns and we went through a pile of over 200 possibly non working psu's pulled from various different computers and it took a matter of 45mins to test them all. it was WAY easier to use the ps-224 than a DMM or a mobo. THAT is what the ps-224 was intended for and it performs very well.
as to your reference to "scientific instruments" as i said it was not....
i consider scientific instruments to be very accurate. like i sad, the ps-224 performs its job well but its not entirely accurate. if it was close down to .001 or even .01 i would not have said that but its pretty far off. 0.17v is quite a bit off and that will make a difference in such low voltages that computer psu's provide. a 3.3v rail thats running 3.13v would most likely cause sata devices to "act up" or might also put strain on motherboard components as well.
