D70E 10. MPP The D70E is equipped with a Permanent Weight Memory (MPP) for storage of weight data referring to each weighing operation in a permanent memory. This memory allows data to be transferred to an external peripheral unit, along with an identification code, which is assigned autonomously by the terminal.
D70E 10.2 Operation The operating mode of the MPP is established during installation. Operating modes are divided into two groups: 1) the user acts on the terminal, in particular on key , to save and transfer weighing information; 2) the user acts on an external terminal (e.g. a PC) on the basis of the methods envisaged by the type of software used.
