The GF312V2S three-phase reference meter integrates comprehensive and highly reliable interface configurations, enabling efficient on-site calibration and intelligent data management. It comes with built-in USB, RS232 and Ethernet ports, while Bluetooth and Wi-Fi are available as optional modules to ensure stable connection with computers, mobile applications and external printers.
Designed for synchronous meter verification, the unit is fitted with 3-channel pulse input and programmable pulse output, as well as an optical sampling port dedicated to energy meter testing. It adopts a 7-inch 800×480 high-resolution color touch LCD, which clearly displays real-time waveforms, vector diagrams and test results for intuitive operation.
Supporting connection with an external keyboard and thermal printer, the device simplifies field operation and on-site report printing. All interfaces feature reinforced isolation and circuit protection, fully complying with CAT III 600V safety requirements to maintain stable and reliable operation under complex and harsh field conditions.
