A3C & X-MAGNETS AND PMF.

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,

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.

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.

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.
