Multi-function electric energy meter on-site tester

DNC-3C Multi-function electric energy meter on-site tester is a high-precision testing instrument that can measure electrical parameters verify the electric energy meter and judge on-site wiring. The instrument is equipped with high precision and high linearity PT and CT, so it has high measuring accuracy when testing various electrical parameters. It is equipped with clamp-type current transformers. Users don't need to disconnect the current circuit to wire easily with them on-site. The instrument uses a high-end embedded control panel dedicated real-time multitasking operating system and a 10-inch large-screen color LCD monitor. It uses an English graphical operation interface with English prompt information. The man-machine dialogue interface is friendly. It has the functions of vector diagram display and wiring judgment, which can provide a reliable basis for checking the correctness of the circuit. It uses the capacitive screen touch operation which is a good handling feel and easy to learn. It has built-in large-capacity data memory, which can store a maximum of 60,000 groups of data and can be extended indefinitely. Users can upload the history records to the computer with the U disk and can also use the background management software of the instrument to achieve computerized management.
