There is no point in doing that. He will ony measure the supply voltage.Measure it with the source attached?
Yes. Exactly. Exactly the point. Is that not what he seems to want to measure?There is no point in doing that. He will ony measure the supply voltage.
10 MΩ nput impedance - do the math. It can't.An oscilloscope could read the volts tho right, just multimeters cant.
That is not what i ment. If you hook a cap in parallel with a power supply and measure the voltage across it (with the supply still on it) then you are mearly measuring the voltage that the supply is giving you not the voltage that the cap can hold.Yes. Exactly. Exactly the point. Is that not what he seems to want to measure?
I'm actually making my own capacitors, so I dont know if they are functioning or not, I get farad readings out of them, but they are too small to test for real. If I hooked em up to an oscillator I can tell, because the led will turn on.
So I've got an oscillator circuit on the way.
I doubt it. Do you know of a multimeter with a response time less than 2mS?Still you could do an ohms test with an analog multi meter. you should see the resistance rising as the capacitor is charging up.
The input resistance of a multimeter is 20 million ohms. Adding 1k will make a VERY small difference of 0.005%.Maybe you could put a 1k resistor to the probe, then times the readings by 1000.

The discharge time of 2 thousands of a second is too small for a multimeter to measure the voltage. Also your vision will not be able to see the numbers.
