I can't get my head around this. Let's say you produced the world's first multimeter and want to determine its accuracy what do you do? Or consider this scenario, you manufactured an RF signal generator that you want to measure its amplitude accuracy and cross checking with another similar product is not an option what do you do? I am not concerned with these two cases specifically(if you know how these two work don't hesitate to share). I just want to learn how accuracy of anything is characterized. When you coross check with something more accurate you sure need to cross check the more accurate device with another more accurate device.
