Clever fuckers or electrical engineers. and shit.

Check out the 'occupy' thread! The inaccuracies from the resistors in there are off the chart!

2x for best post

Akzle there are online calculators that allow you to plug in any value for R and it'll spit out a circuit that has exactly that resistance (allowing for uncertainties)

well fuck the lottaya.
Bogan, despite being 100% fucking wrong, you put me in the right direction, thx.

139kR. New banana chasis socket. Win. Handy dandy trim potentiomnomnomiter, got me the value i needed.
Increased r on 10v rather than trying to bring down 50.
Wil pix later.

derp derp.

while trim pot meas 139. it should be a *calculated* 100kR. and it seems, that it should be, so i'm going to pull the cunt apart again, and swap out the 3 i put in, for one, at 100kR.

pics anyway:

[COLOR="#139922"]okay, so's i has an analog multimeter. on it it has 10v dc and 50vdc, the face is scaled also for .25ma and 250vac.

OK if you want to use the 10v range to measure voltages up to 20v just get two identical resistors. The value isnt really important, anywhere from 1k to 100k will do at a pinch, but I would suggest 10k.

Then put the resistors in SERIES.

Place the resistors across the voltage you wish to measure. Exactly 1/2 of the voltage will be evident across each resistor.

So measure across either resistor with your multimeter to get your result.

yes. or. since i've done this already, i could just put the right resistance in so i've got a nifty 15v range banana socket.
