The Yaohua XK3190-C2 weight display manual provides setup, parameters, interface and operation instructions for the weighing controller.
The XK3190-C2 is a weight display controller that uses an MCS‑51 microcontroller and high‑precision sigma‑delta A/D conversion to convert and show weight. It supports connection to resistance‑strain sensors for batch, cumulative and packaging scales and offers functions such as panel calibration, parallel printing, multi‑language records, data storage, clock/calendar, zero‑setting, serial communication, tare, analog output and relay control.
This manual covers the device overview, technical specifications, hardware layout and connector details, parameter setting and calibration procedures, normal operation steps, control processes, troubleshooting, and communication protocols for RS‑232/RS‑422 and large‑screen display interfaces. This manual is written in Chinese.
