Okay on your having 3 such meters, very good.  And it is always good to know they are calibrated or
measure within  their tolarence range

In fact I have no problems with my or your multimeters, I would like to know the resistance your meters
have, how they differ from my M-830B type as I described  It would cost you only 2-3 minutes to check. 

Thanks,
Gyula

Intersting, never though that multimeters can also test eachothers, I usually swap them during testing such assuring that results are not obtained by one which has went wrong just while before, also I have small electronic resistors with known resistance which I use sometimes for presissions control.


So, I was connecting blacks and reds together on three variants of pairs, when swiched on 2000 ohms its displaying just 1 and if swithed on 2000k then its oscilates for a second or two then displays steady 1 also, is it all right or I need to by 3 DMMs again for measuring of hundreds of ohms and hundreds of volts. I beleave that high fidelity DMMs are neccessary for microcircuits of electronics and in electromechanics some rough measurement are acceptable.

Hi, thanks for trying to do the resistance measurements between the DMMs. 
Yes, the connections sound ok and please set one of your DMMs to the 2000 k position (not 2000 Ohm) and set the other DMM to AC 750 V position, ok?  I do not know why you see 1 on the display because I have only one such meter (M-830B) and not two.  With my other DMM shown in my yesterday picture I do not see any oscillations on the display when I check my M-830B. 
And I cannot test my other DMM with the M-830B because the latter is able to measure up to the 2000 kOhm value and the other DMM has 10 MegaOhm resistance in DC ranges.

I suggest you to try also the DC 1000V  or even say DC 200 mV positions on the 2nd DMM when the 1st DMM is in the 2000 k position.
Also, if you have a 3rd such DMM, then try to set it also to DC 1000 V and try to connect it in parallel with the 2nd DMM which is also in DC 1000 V position: what does then the 1st DMM show in its 2000 kOhm position. If the latter now displays other than 1 without much oscillations, then we may or still may not deduce something on the resistances.

EDIT: it just occured to me that if you have at hand any high value resistor like 1 MegaOhm or even several hundred kOhm, then you could connect it in parallel with the 2nd DMM set to DC 1000 V (or AC 750 V) and see what the 1st DMM displays. (you can check the high value resistor with any of the DMM in advance to know its exact value).

Guyulasun, please realise that you generate U-conversion of discution about


GENRERATORS OF ELECTRICITY
https://sites.google.com/site/ageofmagnetizm/home/magnetomechanics/hyperefficient-generator


 into discution of multimeters,
and discusion about


METHODS OF GENERATION OF ELECTRICITY
https://youtu.be/oTgOJcxmjCw


into discution of methods of measuring of Electricity.
I feel reluctance to this U-conversion and will produce resistance to such efforts.
 :) :D ;D

Hi ageofmagnetizm,

Here is what you wrote 2 days ago, notice your 2nd point:

There are two reasons I'm posting here:
1. To learn about similar experiments and hopefully replications of similar constructions, at least
such simle as I have discussed at the beginning of this post;

2.and the second reason is to learn oppinions and suggestions about testing, constructions and
a theory of the processes.
.....
Otherwise keep asking, adviceing, suggestig, even teaching. Why not?

This means that what I suggest for you to measure the resistance of your meters is not off-topic at all
because it is exactly on about testing and learning not only about your setups but the meters you have.   
I find nothing wrong with how cheap or how expensive DMMs someone uses, I am not here to criticize
someones's meters.

Gyula

PS if you reduce your uploaded picture size to have a max of 900 to 950 pixels horizontally,
instead of the 2048 pixels you have above,  then we do not have to scroll horizontally
back and forth to read the posts.  You can find the Modify icon at the upper right side corner of your post above
and you can remove the high sized picture. Then use a picture editor (like Windows Paint) to resize your original
picture from 2048 x 1536 pixels to a lower size, with 900-950 max pixels horizontally instead of 2048.

Many similar tests with various loads has produced the same result and on following picture generator is testing with certifyed 100 ohms / 500 watts immersion water heater where AC current causes increase of temperature of thermoelectric resistor where rising temperature causes increase of resistance of electric circuit.[/size]

above is link to short video where AF PMG-MMEIR 4E8M is being tested with no load connectet to circuit, and then video is paused and continue with testing of generator connected with 5 ohms electrical inductor, and paused and continue with testing of generator with cold thermoelectric resistor with measured 77 ohms. During three tests multimeter display same approximately 260 AC voltage what is obvious manifestation of expected Zero Magnetomotive Feedback and unexpectually discovered Hyperefficiency where output electric power is many time greater than mechanical input power of drive motor.




Shall continue...

hi ageofmagn,
either intentionally or not, your measurment is not the proper one,
good job anyway

Sparkmen,
thanks for such brief and elogant expression of your mind,
now I know your attitude and have to guess what you actully mean.
Just read all previous discussions of measurements which went to be fullish and
do not repeat same suggestions for the second time.

ageofmagnetizm,
not meant to offend, even if you connect 10kw load and measure voltage in series, you'll still have 260v...
will be nice to see what voltage come across any load, will give more info

A wise man listens to good advice.  A foolish man ignores it.

Sparkman,
Please explain what you mean "across", have I tested along or in digonal,
and how do you calculate power?

dear Taras, well...,  in this case calculating the power will be more confusing.
try a easier test, make some hot water with that boiling device.

For those having "wishes" - I recomend to read the COMMUTATOR page of my website:


https://sites.google.com/site/ageofmagnetizm/home/ageofmagnetizm-commutator


paragraphs 3. and 4.


And once saying that something is wrong, please specify why and what would be right instead,
Sparkmen, can not you explain proper methods of meassurement such as Gyulasun did, providing
the link to technical papers, such as citation:


{ See Figure 2 in this link http://www.bristolwatch.com/ele/transformers.htm[/font] where power measurement is explained in a mains transformer: an AC ampermeter is shown in series with load resistor R1 in the secondary coil too. Your generator output coil corresponds exactly to the secondary coil of this transformer when its output power is to be measured. But you will choose a known R1 load resistor so that you can use V2/R1 formula for output power by measuring only the AC voltage across R1.  }

ageofmagntetzm, here is a good start for learning how to use mutlimeter

Also nice link, Sparkmen.
Although there is explanation for small DC battery and suggestion that
Resistance of lamp is much lower than resistance of multimeter causing
 that most of current must to flow through the lamp.


This does not exactly matches my AF PMG-MMEIR 4E8M giving up
max 270 AC voltage at approx. 100 hertz when drive motor is switched on
Max 1400 RPM and accu is just fuuuly charged.


Though I foud one small LED 230 AC voltage and 50 herts and it has survived experiment
Producing usual white light so indicating that some current flows through it.
Although I had to tune pressure on switch button of drive so that RPM was some lower and
Multimeter was showing 190 to 230 AC voltage. Leads of multimeter and generator were
Simultanously connecting on terminals of the LED and resistance was measured before and after
Running rotor and meassuring AC voltage and showing almost same resistance that is measured
When multimeter is connected just to terminals of generator alone.


Wow, I does light, though lamp is just 1.1 watts max. Power,  - obviously that such results are inconclusive
And some lamp for at least 20 watts need to be found and survive weird freguency and shine...


Anyway, testing at Scientific Research Laboratory has been sheduled and I've seen there all kind of very cool looking
Equipment and smart looking guys, so that I have no doubts that they'll do measurements properly.
