EMJ,

No one is making "wild claims".  I watched the videos.  Nothing in those videos verifies the scope math when measuring complex waveforms with large amounts of reactive power. 

CaptainLoz is measuring a very complex AC waveform that likely has a large reactive current component.

The simple test previously suggested is quick verification that the scope is measuring real power and not VARS or some other weird possibilities that can happen if the math channel is not programmed correctly.

When the two 0-5VDC square waves @50% are in phase, the expected math output would be 12.5 watts (5V X 5A = 25W for 50% of the time = 12.5 watts).

Shifting one of the square waves 180 degrees simulates a current and voltage that are exactly 180 degrees out of phase, so the scope should now read zero watts (5V X 0A = 0W, 0V X 5A = 0W).

This quick verification ensures the scope is reading real power and not VARS or some other weird values that can occur if the math is not programmed correctly.  It would take less time to perform than it took to make this reply.

Some make wild claims: "the math is not properly programmed" on the scope.

Honestly, this is so absolutely stupid to suggest! Desperate, COMPLETELY desperate attempts to sweep this major problem they have away!

TWO Scopes, both A x B Both Calibrated, both tested using Standard DC Methods with Equipment. How do we test our equipment?

Here:
   1: Test the Scope using Known DC Load: https://youtu.be/x17HQCiVHW0
   2: Test Equipment again after Scope Calibration: https://youtu.be/ol-3VZJaqys


DAMN! Some people are silly idiots and have no logic what so ever in their minds! This is the absolute dumbest suggestion I have ever heard! It is IMPOSSIBLE to have the Scope Math wrong, if its been tested under DC Conditions and found to be Correct!

Some, are completely wrong, talking from an uncontrollable hole in the middle their your head. Use commonsense, stop talking RUBBISH! Illogical, nonsensical rubbish! Stop with all the Diabolical Stupid! Tell your uneducated Numptys to go and educate! They make you look even dumber when they come and make dumb idiot Posts!

Best wishes, stay safe and well in these Dire Times,

EMJ,

I am not making any assumptions.  I am merely pointing out an observation.

In video #5 @ 7:30, the DC power supply is feeding 17 watts into a circuit that is lighting two small incandescent lamps that appear to be series connected.  Thanks to CaptainLoz's response, we know these lamps draw .2 amps at 14VDC, or 2.8 watts, at their rated output.  The series connected pair would therefore draw 5.6 watts when connected across 28VDC. 

The lamps in the video do not appear to be overdriven to any large extent, but even if the pair of lamps were being overdriven by a factor of three times their rating (i.e., 16.8 watts), the circuit would still not be 100% efficient.

It would take very little time to connect the series connected pair of lamps directly to the DC supply to confirm their power draw at similar brightness.

These people, are, automatically basing their assumptions, entirely, on the Oscilloscope readings being incorrect!
...

Logic and Reason does not exist here!


P.S: I will continue Deleting Idiots!

EMJ,

You can't be serious.  I think you need to step back and look at this with much less emotional investment. 

A string of pulses is being fed into circuit having both inductive and capacitive reactances, with some apparent tuning using a variable capacitor, and you do not believe there will be a reactive current component flowing in the circuit?

I don't even know how to respond to that.  Hopefully CaptainLoz is a bit smarter and will understand the logic of the suggested square wave test.  The point of the test is to ensure that any current out of phase with the measured voltage is not counted as real power.  Its a very simple test. 

By the way, the square wave used to simulate the current input can be reduced to 500 millivolts if the scope's current input channel is set for use with a 0.1 ohm CSR (as opposed to a 1 ohm CSR). 

If you still don't understand, please feel free to ask...

WHAT ARE YOU SMOKING!!!

Voltage and Current Phase is almost purely IN PHASE! Pure, Real Power! Power Factor of pretty much: 1.0

There is no Reactive Power in there! What are you SMOKING! Do you have any idea how Stupid your post sounds? Man Alive, go and retire or something, you are so far off the mark its not funny!

What Non-Sense you keep writing Picowatt!

Best wishes, stay safe and well in these Dire Times,

Hello All,User WhatIsItis on moderation, cause he has slandered permanently Chris...
Sorry, I am very busy with other things and can not moderate much... but with the function moderation single users,I can better see, what they post, before the postings go online...
If there is a claim, that someone runs a scam on his own website, I guess there would be comingother users forward, that feel being scammed... so are there any victims yet ??

Regards, Stefan.

Thank You Stefan!

There is no Scam, that was a false accusation! Some kind people, through free will, can make a donation if they wish, to help support the costs of my website, other than that, I receive no financial incentive to do what I am doing. I do not run ads or anything! I do this for Free! I do this for Love!

We have a replication of My Work, CaptainLoz has shared his work publically and we are trying to come to a conclusion. With brand new, calibrated equipment, we can not find an error. Many are trying, as yet unsuccessfully.
