This may be a limitation of the RMC75’s Axis Tools and Parameters; I am not as familiar with the RMC200.
Thank you! We appreciate hearing from customers about their needs! Since we released the LC8, we have received quite a few requests for a load cell input on the RMC75. It is possible, and we are considering it. For the moment, redesigning boards due to supply chain issues is keeping us too busy to consider much else, but your request has been duly noted.
