This document provides technical specifications and operational instructions for the 500 Series V1.3 Intelligent Digital Weighing Transmitter. Key features include a DC 12-26V power supply, 12-16 bit data acquisition accuracy, and dual output capabilities for RS485 Modbus RTU communication and analog signals (0-10V or 4-20mA). The device supports one-key zeroing and automatic zeroing functions to ensure measurement stability.
The manual details the physical dimensions, button functions for calibration and zero adjustment, and comprehensive communication protocols. It includes specific instructions for calibrating current and voltage outputs using known weights, explains the Modbus RTU command structure for reading and writing parameters, and lists detailed register addresses for configuration. This manual is written in Chinese.

Long press the clear button for 3 seconds until the light turns off to unlock, then long press the clear button for 3 seconds again to clear the transmitter.
The formula is: 16mA gain output current = (Known Weight / Sensor Total Range) * 16mA + Zero Point.
Send the command 01 10 9C7C 0002 0400004E20 to write the sensitivity value (e.g., 20000 for 2.0000MV/V).
