Re: "f6" "f7" blue esr issue
i did try it out and it was very hard to set it. the meter was soo jumpy i had to be really really slow sometimes is would read and other times i needed more of a turn on the dial to make it read right. as for measuring i will retest it tonight.Leave a comment:

Re: "f6" "f7" blue esr issue
i have found the 100k and the 220k not testing their true values unless i am testing them wrong. 100k is measuring about 50k and 220k is reading about the same. i will replace and see what the result is.Leave a comment:

"f6" "f7" blue esr issue
i know this must be a stupid question but here is goes bought blue esr meter and built it was so fun. I am a novice-medium knowledge in repair person on a good day lol. yes this is my first kit since i was a kid.
Now when i start her up all seems good, so i though i would do the self test feature on the meter so i read the info on how to do this properly so i did this
(Before doing the self-test, it's very important to first set VR1
to the center of its adjustment range, short out R30, 100R and make sure that the meter's supply voltage is
in the range...
