Multiple digital load cells forming one or more weighing scales are connected together and to a common master controller in a local area network. The digital load cells are polled by and provide weight readings to the master controller. The weight readings are combined with a load position correction factor for each load cell and summed to provide a weight indication corrected for load position. The values of the load position correction factors are determined during set up of the scale and stored at the master controller. An individual load cell can be diagnosed remotely and replaced if defective. A new load position correction factor is determined and stored for a replacement load cell.
