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.
