Accuracy, Precision, Resolution, and Sensitivity

This will dictate how the sensor responds. For example, take a sensor that is rated for 1000 units with an output voltage of 0-1 volts (V). This means that at 1 volt the equivalent measurement is 1000 units or 1 mV equals one unit. However the sensitivity is mV p-p so it will take two units before the input detects a change. The Measurement Computing USB-1608G Series Example Let’s use ...
