Color is kind of useless, though. The details are in that thread in EEVBlog, starting around page 54 or so. There is also discussion on the EEVblog thread on building a protection circuit, but I do not recall on what page of the thread. You MUST discharge the caps by shorting their leads before attaching, as the surge from stored energy can fry these. Aside from not having a battery clip somewhere on the assembly it seems to be pretty solid, and works a treat for figuring out what those little tiny things are without having to bust out the magnifier. TV antenna booster admin July 22, 34 Comments. Basically yes, if you attach wires to testpoints, but what in reality it would be testing is the combined effect of the circuit, not the component. More on that later. A long time ago when I was part of a local microcontroller club I would recommend this device to people to built. In winding inductors for RF designs, this measuring circuit allows the designer to know exactly when the desired inductance has been achieved.
Their customer database paid off when it recommended a $22 transistor / component tester.

I've been seeing those testers around quite a bit.

If the polarity .
My understanding is that it is pretty close to the original design. I really like it. The EZM Electronics Studio version is probably my favorite because out of the box, it supports the fullest range of options from the mainline firmware and because it uses a socketed MCU and mostly through-hole components with appropriate tolerances. I have one of these for a while.

The document even explains some of the shortcomings of the Chinese versions of the tester, including using a zener diode where the original schematic calls for a precision 2. Report comment.

But then it does come from China.

My most expensive gear was made in china, and I have moderately priced gear that was both designed and made in china.
The English PDF is pages, explaining theory of operation, the circuit itself, and the software. This costs less than making one yourself, open source software, verry usefull. Now I would like to come back to this webpage and read more but it this web page used up 3.

You MUST discharge the caps by shorting their leads before attaching, as the surge from stored energy can fry these. It works well but how can i increase gain?

|I really like it.
Capacitor jumps high and decays low, inductor starts low and exponentially builds. Pls send right up on fire alarm using thermistor. In winding inductors for RF designs, this measuring circuit allows the designer to know exactly when the desired inductance has been achieved.
These testers have been around for ages.
