UDNB-3S Handheld Three phase Energy Meter Field Calibration Instrument -112
The UDNB-3S handheld three-phase energy meter on-site calibrator is a reference for the Micro An Power R&D Center's DL/T826-2002 and DL/T448-2002 A high-precision power tester developed and researched in accordance with industry standards for integrated energy meter calibration and wiring judgment. The handheld three-phase energy meter on-site calibrator is mainly used for measuring current, voltage, phase, active power, reactive power, and other electrical quantities. It is equipped with high-precision and high linearity voltage transformers and current transformers, as well as photoelectric, manual, and pulse signals to ensure the accuracy requirements of the tester for various parameters. The handheld three-phase energy meter on-site tester is also equipped with clamp shaped current transformers, making on-site wiring simple and easy to connect without disconnecting the current circuit. The handheld three-phase energy meter on-site calibrator adopts a large screen color display, human-computer interaction interface, and Chinese prompts, making it easy to use and operate.
