Kit Penentukuran Meter Tenaga Elektrik HZ-1011P 3 Fasa

I. Gambaran Keseluruhan

Multi-function electric energy meter on-site testing instrument is a high precision testing instrument that can measure electrical parameter and verify electric energy meter and judge on-site wiring. The instrument is equipped with the high precision and high linearity PT and CT ,so it has the high measuring accuracy when testing various electrical parameters.And it is equipped with the clamp-type current transformers . Users don't need to disconnect the current circuit to wire easily with them on site .The instrument uses high-end embedded control panel and dedicated real-time multitasking operating system and 10-inch large-screen color LCD monitor . It uses 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 the reliable basis for checking the correctness of the circuit. It uses the capacitive screen touch operation which is good handing 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 the computerized management.

The instrument is made of engineering plastic shell designed and  moulded independently by our company. The instrument is beautiful in appearance and practical. It is easy to operate while testing on site. When the instrument is operated, its back bracket can be opened. So it can be operated by hand or on the desktop. The instrument is equipped with high strength self-stretching handle. It is convenient for the operator to hold the instrument with one hand.
