Re: Mtester

Think I overpaid and was fooled by this guy. Sold me some caps back then that were way out of spec too but said they were one of the best available.
The tester was a kit too, had to assemble it and cost me shy of 30 euro's.

Re: Mtester

Haven't gone through the calibration section yet but saw the T4 as you described it to be in the pdf. So if I understand it correctly, I have been sold a chinese clone instead of a legit version that I was told it was.

Re: Mtester

Thanks! I will have a look at that pdf

Re: Mtester

This is my little tester and some of the caps I got.
Strangely enough some of the top tier brands were completely out of spec and some brands that I haven't heard of before like Tosin were perfect. But then again, it is not known where those caps were used and if they had a hard life or not.
Some of you may not agree reusing used or salvaged caps but I think when they are in spec and still seem ok, why not ...

Hi all, new here and wanted to ask you guys if you can help me understand the device I got.
A few years back I got this Mtester at a local shop but noticed that it sometimes seems to have some errors?
Secondly, I would like to understand how this thing works when for example testing caps, if it needs some kind of calibration of some sort.

The error it seems to give is that when I measure a (used) electrolytic cap and place the leads in socket 1 and 3 it sometimes displays that the cap has zero ESR (ESR reads 0.00) But when I place the same cap into lets say socket...

Hi all, My name, obviously is Danny, I am in the process of selfeducating in electronics and that is sometimes a bit of a hurdle as I wasn't very good back in the day in mathematics. But hey, we'll never learn if one doesn't make the effort.

But now, I like to take on vintage audio and see if it can get back in working order. From cleaning down the outside and insides to making it into one happy piece of equipment.

Got me handed some stuff and the first the first thing already came up. Well what better...
