given a processor batch of 1000 resistors moving on the conveyor belting in a large factory. the resistors is value at 10k ohms each but when the resistors reach the quality control, some of the resistor has been rejected caused by failure in manufacturing.the high quality measurement is used to determine the failure. describe the instrumentation terminology in measurement of a system above with explaining the important in:- -reliability -sensitivity -repeatability -precision -range -resolution -linearity -hysteresis -error -accuracy (answer must related to the scenario above)
