We connected the load cell to an LCA-1 Loadcell amplifier and then to the DI-808 on the analog channel. We have tried calibrating using a known weight. Each time you weigh a known object 80kg on the loadcell and try to set the DI-808 with the known weight, the reading on the digital column shows values unrelated to what we set. Clearly the readings on the DI-808 changes with changing the weights on the loadcell but the readings aren't related to what is being measured. We don't know why. Please help
