<html><body>The device is designed to automatically fill a package with a pre-set weight using a pair of scales. Introduction: This module is intended to integrate seamlessly into an existing machine, enhancing its capabilities for precise weight filling. Functionality: Upon initiation, the device activates the first relay, initiating the monitoring of the first scale until the preset weight is reached. Once achieved, the first relay deactivates, signaling the second section to commence, activating the second relay for the weighing process. Control then cycles back to the first part, initiating a new cycle. Integration: This module is designed for easy integration into the machine, providing an efficient solution for automated weight filling. Operation: The program incorporates additional buttons for adjusting the target kilograms and fine-tuning the scale. Users can also perform scale calibration and access supplementary information via Bluetooth connectivity.
