Measuring small electrical signals has always been a challenge. That's why Keithley started publishing its Low Level Measurements Handbook, now in the 7th edition. In 200+ pages it describes nearly two dozen specific examples for measuring:
- Low current
- High resistance
- Low voltage
- Low resistance
Along with these test descriptions, it also covers a wide range of measurement science topics so you can make the best measurements possible. Common sources of error, ways to minimize these errors, and the science behind measurement equipment are all covered in detail. It is no surprise this book is considered by many to be the authority on precision low level DC measurements.
