#82631 - I guess, standard practice for interchg Responding to: Steve M. Taylor's previous message |
Use a Dallas one-wire serial memory on another three of pins in your cable from the Rogowski - read the calibration constants from the memory when you boot up.
When I did postal scales, we glued a small serial EEPROM (24Cxx) onto the loadcell. That contained all calibration info and this allowed replacement of the loadcell without turning trimpots or whatever. Erik |
