GF211D Voltage Wiring Connection Step-by-Step Demonstration

Every set of GF211D phase meter is supplied with standard voltage connection accessories tailored for multi-scenario voltage measurement demands. The 1.5m extended voltage cables facilitate wiring in deep, narrow control cabinets, and the clip opening size adapts to standard terminal blocks of power equipment. Clear marking on each voltage lead corresponds to U1, U2 and COM terminals of the host, guiding users to finish standard wiring for single-phase voltage detection, two-channel phase comparison and three-phase sequence judgment. The voltage input circuit maintains stable 0.5-class measurement precision after correct wiring, and the ultra-high input impedance design avoids load effect distortion on weak secondary voltage signals. For power factor and load characteristic testing, voltage lines connect U1-COM while current clamps match I channels, realizing synchronous acquisition of voltage and current signals to judge inductive or capacitive loads. All voltage connection accessories are subject to factory withstand voltage testing, matching the whole machine's wide temperature adaptability from -10℃ to +50℃ for long-term outdoor and indoor wiring testing.

Calibration of GF312V2 Energy Meter Calibrator | GF333V2 Reference Standard Meter with GF302D1 Three-Phase Power Source

 We used the GF302D1 portable three-phase tester as the standard three-phase power source.

In this test, we used the GF333V2 high-precision three-phase reference standard meter to calibrate the error of the GF312V2 portable field energy meter calibrator.

The GF333V2 high-precision three-phase reference standard meter has an accuracy class of 0.01/0.02. It supports full-range voltage and current measurements, harmonic analysis from the 2nd to the 63rd harmonic, vector diagrams, and waveform display, providing traceable, ultra-precise power data that serves as an authoritative calibration reference.

All equipment complies with IEC, CNAS, and CE standards.
