CD194Z network power meter is designed for power system, industrial and mining enterprises, public facilities, and intelligent buildings. It can accurately measure common power parameters and has flexible display and programming settings. The CD194Z series meters have a high performance-to-price ratio and are widely used in various control systems and energy management systems.
This manual describes the CD194Z series network electric meter designed for power monitoring in industrial, commercial and building automation applications. It explains the meter's high‑accuracy measurement of voltage, current, power, energy and other electrical parameters, and details the LED display and programmable keys.
The document covers technical specifications, mechanical dimensions, installation procedures, wiring diagrams, programming menus, function outputs (pulse, analog, switch), and alarm configuration. It also provides communication settings for RS‑485 MODBUS‑RTU integration with PLCs or SCADA systems. This manual is written in Chinese.

Mount the meter in a distribution cabinet by drilling a 111 mm × 111 mm opening, insert the meter, secure it with the fixing clamp and screws, and connect the terminals as shown in the wiring diagram.
The meter provides a digital RS‑485 interface that follows the MODBUS‑RTU protocol for networked data acquisition.
Use the XS1 control word: XS1=0 for automatic cycling, 1 for three‑phase voltage, 2 for three‑phase current, 3 for active/reactive power and power factor, 4 for frequency, 5 for active energy, and 6 for reactive energy.
The meter offers four analog output channels, each configurable for 0–20 mA or 4–20 mA signals corresponding to selected measurement parameters.
