I did on bread board the Nuova Elettronica ESR meter based on the schematics and data as on this site: https://www.qsl.net/iz7ath/web/02_brew/15_lab/06_esr/index.htm
I'm using a DMM to measure the current. Funny things happening as usual. :lol:
I put any resistor across the DUT leads, it...
Re: russia esr meter
I intended to make the Oleg-GO meter, but could not get all the components. Out of the to-try list, I could get all the components for the Silicon Chip 2005 one, but it's not tuning up at all. It's still on the bread board and not responsive to being calibrated. The DMM I'm...
Good links there :).
Yeah, ulitmately, all of these are being so small these days that they can be put into one unit.
I have reduced the choices to Oleg Go C-ESR Meter, and if there is a way of DIYing the programming, the remaining details of many commercial ones like Blue, EVB, etc are also...
Did anyone try **broken link removed** (Silicon Chip ESR & low resistance Meter, published February 2005) ?
Also, are there any more designs of LCR-ESR meters that are add-ons to DMM?
Well yes, the DMM usually shows well under 50 Ω for the continuity. I skipped the opportunity to test with the bulb or any other device since I took the results of the DMM's continuity test as the final call. The actual Primary coil showed about 1100-1200 Ω and the rewinding of 2500 turns with...
:D Well yes, by hand watching some cricket match or a movie in two instalments, using some rod/screwdriver as spool axes, so as to avoid any folds/turns of the wire. I wanted to make a small gear machine to operate by hand to complete the job, but it would cost a small bit more for just one...
Hello All,
I have an old computer UPS which I took to the repairman. He said a transformer is not functioning and it is better to buy a new UPS instead of replacing the transformer.
I identified the transformer, and on checking the leads, I found that the continuity test for Primary coil...
