With the situation of finding a new multimeter, I found myself lost to the number of available devices on the market. For sure, to find the most suitable device I have to set some requirements. While comparing them, I came to the following point and by this to my question:
Most pro devices have only ampere range with a resolution of 0.001 A (1mA), while semi/hobby devices have ranges for milliampere and even micro-ampere. I saw device reviews on YouTube, where the presenter complained about missing micro-ampere range. While another person on YouTube told the audience that milliampere range is sufficient. So, here my question to the experts:
What kind of scenarios require a measurement of micro-amperes?
For example: Looking at a data sheet an AND gate has "input leakage current" and supply current in micro-ampere range, but when is it necessary to measure this tiny current?
Thanks for all helpful answers.
