Using the Yosoo GM328: a guide for radio and electronics experimenters Kindle Edition

The GM328 comes by itself, wrapped in bubble wrap with no instructions, there are many sites on the internet that go into very great detail of what the GM328 does, lots of theory behind the operation. This book was written for those of us that just want to use it, put the CBE leads in these slots and this is the reading and what it means, put the resistor in these slots and take the reading, same with capacitors, I haven't tried it out on the coils of an SDR kit but I think it would make the measurements, the author also covers a few other functions. If you want a quick and easy guide to using the GM328 this is a good start, if you want to get into technical details there are quite a few sites on the internet that should interest you.

What can I say, this thing is amazing for the money! You just have to solder 3 leads to the board and your off! Press the knob to turn it on, turn it to choose your poison and after connecting the leads to your component in question, press it again and BOOM you have what you know what your working with. Great for capacitors to be sure. I took a batch of caps that tested fine as far as their capacitance before I got this unit and after testing them with it I found the ESR was way out on 5 out of 40 of them and the voltage loss was double to triple what it should be on about 3 out of 40 of them making my batch of recycled caps ready for prime time.

Although I've had them GM328 for some time, I ran across this guide. I always wanted to get a better understanding of the GM328 but there seemed to be some confusing information on the web. This guide is well written and provides real world examples and explanations on how the unit performs its tests. Now that I have that knowledge, I am better prepared to understand the results I get from testing various devices. Well done!

This manual explains all the functions of the GM328 in a very straight-forward method. It also exposes it's strengths and weaknesses, it's history and technical/functional details. The book goes into alternative ways to measure components, how to match transistors and a very thorough explanation of exactly what ESR is. It has a perfect balance of information for both the beginner and advanced user. The troubleshooting section is valuable, as well. You won't regret buying this book. Thank you, Mr. McClanhan!

did I buy this I do not remember... going to have to paly my age card will be 78 soon

Works good! Reads small capacitance very well

Makes using the GM328 a reality since no info on how to use any of its functions comes with it !

Much more than a user guide. Besides explaining the use of the instrument it goes in depth about why it performs the way it does. Additionally, it covers some handy circuits and troubleshooting. I'm very pleased with my purchase.

quiero el libro en Español y ademas el aparato medidor de ESR

Very good manual, i found it very useful
