Good morning to all of the forum, I request your help for the calibration of a Metrology Mod scale. BCP15 has 24 buttons is counter and weighs poorly, if you can support me with the steps for calibration or the manual would be of great help. This is a photograph of the card, there is a loose cable from port DB15 to add a platform in terminal J9 corresponding to JP. I hope this additional information could guide me for calibration. Regards.
