    Chapter 5 - Calibration The expected output from each load cell/point depends on the mV/V rating of the load cell/point and the weight. For example, a 2mV/V load cell/point will respond with a maximum of 10 mVDC at full weight capacity of the system which includes the weight of the vessel and the weight of the product as measured by the load cell/point.
