Reactive power - Reactive Generator research from GotoLuc - discussion thread

I thought you had it sorted some time ago?

I have sorted the part where you add channel A and B,and get the math trace up on the screen,but still cant find where to read the result of the sum,other than a whole bunch of numbers that make no sense to me.

Can you post a screen shot of A x B?

Maybe the result is buried amongst all the numbers.

Okay, something new learned!... DC coupling when wanting accurate math results from an AC source.
Not a problem. I will do that from tomorrow on.

Thanks for finding that one.

Well, you should be using DC Coupling for 99.9% of your scope measurements actually.

Hi poynt and all,

here is a video update with the scope set to DC coupling. I'm still questioning the channel 2 Inversion.
Can you please confirm which way it is and what is Watts used

Thanks

from a ground base; (common/neutral), the probe on the outside of a resistor is positive for a positive current draw.


- load(+ side) - battery - (low, negative side, scope common) - CSR - (probe, high level is positive current) - (load)


Should not be inverted.  Inversion should be used if you're biased against the positive as the ground reference.
