Title: calibration
Post by: kon on April 17, 2010, 07:59:04 AM
I have a friend that always ask me (with joke) Why always we need to calibrate every electronic device ? If anybody here has an answer for this I will glad to know (The answer can be like a joke but I want also to know also the real answer) Thanks

Well, closed loop devices are self adjusting and components like eg. a transistor are all electronic devices and you don't calibrate them, so perhaps you need to be more precise.

Thanks Soeren, Can you give examples of devices that use open loop control or example of device that need calibration
