Why do you keep starting new threads?
They just waste our time and very soon we will lose patience and just stop
looking at them.
Most people on here have full time jobs or other interests and time is precious. If you consider the large number of queries and the small number of regular contributors I just wonder who you think is going to answer.
Besides which there must be a hundred or so threads regarding esr meters
costing from $5 to $100 - I suggest reading - use the search facility above
instead of writing.

i did searched!!! but no1 gave a good advice or example!
So i looked on ebay and found this and in the feedbacks on it is very good but no1 there is a pro and u cant tell but here there is pros so...
dont b angry with me pls i am sorry but my PSU is dieing and i need tools and good ones and i am a student and dont have alot of cash.
R u crazy! Its 100$ tool.
My teacher build esr meter by him self and working great so y should i buy this in 100$!
Look man notevery that shine is gold, most of things bcuz there is a brand on it is more expencive, for example: u have smartphone with the same proccesors but just bcuz on the phone there is samsung it cost more a lot more.
A lot of people have stated their opinions in the threads linked pertaining to what you asked. Did you read them? If not then do so. If so then what exactly is your question?
This is THE monster thread on ESR meters also has links to eevblog
Features the DIY the Ebay the semi DIY and the Expensive.
Someone on there has all three so that should give you some ideas.
Basically though you have to need one and use it enough to justify the cost of even a cheap one.
I read EBOOK of Testing Electronic Component and found that
"In order to test the small blue resin coated ceramic disk capacitor which has 104 50v specification,it is possible to test this small ceramic capacitor by making use of analogue meter.
Set to times 10Kohm that has 12v output from the probe to check disorder of ceramic capacitor.
It is not uncommon that testing result of digital capacitance meter is okay,But It show shorted reading when you check it with analogue meter."
Is it really possible to test small ceramic disc capacitor with analogue...
I have had with regular AA batteries that leak this meter is expensive new I already replaced the battery battery clips once and the same thing happened again and I am tried of so it is getting modified to accommodate lithium ion batteries that are the same size excluding the positive terminal and removing the battery clips I will have enough room for the BMS protection board
I going to put 3 lithium ion battery in parallel with the BMS protection board and a way to charge the battery externally and heat shrink the battery pack and use a JST connector so I easily remove the battery...
Recently I've noticed that some ShopJimmy backlight strips don't have double-sided tape installed upon them when an application calls for it, and I must purchase the tape separately. In a recent chat conversation with a customer service agent I told them if this tape wasn't applied when it was called for I would begin to consider ordering my backlight strips elsewhere. It looks like this time may have come.
I want to change the scale of an analog meter, to monitor the charge of an li-ion single cell, so the needle at the end would point 4.2 volts and the 0 on the meter would point 2.5 volts or so, i tried to add diodes or a zener in series with the meter but the changes of the ambient temperature also changes the voltage value on the meter
I wonder how i can accomplish this so the meter would be precise at any temperature ?
About a month ago we had a transformer jumper wire that burned in two different places between two transformers caused over $200 thousand dollars worth of damage to VFD drives at least 10 of them and a memory card and quite a few power supply as well
Now we have most of the equipment that got damaged back up and running except a feeder that has issues and we are waiting for some parts for
Now we also have another piece of equipment that was blowing fuses on the 110 volt controller switch circuit with the “E” stops and one switching power (24 volt) supply and a transformer...
