Just got VOLTCRAFT VC135 multimeter. Testing cts 500 k pots, and the multimeter on 20M setting, shows 0.47. Tested my Jackson DK2S guitar, and tone pot shows pretty much the same: 0.44 . Tested volume pot of that guitar, and it shows 0.02 . So, i am just confused overall. Looking at youtube videos, people are testing with multimeters 500k pots and it shows .567 . i am testing it with this one and it shows me 0.47 . Can someone explain me, what this is all about?
