PRODUCT INTRODUCTION
Xtester-ETCR6900 Flexible High Current Clamp Meter is carefully designed and manufactured for field testing of AC large current. Widely used in electric power, communications, meteorology, railways, oil fields, construction, measurement, scientific research and teaching units, industrial and mining enterprises and other fields. It is especially suitable for places with dense wiring, transformer core current testing against the wall, thick wire cable testing, relay protection, thyristor rectification, frequency conversion speed regulation, semiconductor switches, power electronic conversion equipment, arc welding, etc., where the signal is seriously distorted. Current testing in industrial environments. The flexible current clamp, namely Rogowski Coil (Rockowski Coil), adopts advanced Rockwell Coil (or Rogowski Coil) technology, which is a circular coil wound evenly on non-ferromagnetic material, without hysteresis effect and almost zero phase Error, no magnetic saturation phenomenon, high linearity, strong anti-interference ability. The output signal is the differential of the current with respect to time. By integrating the output voltage signal, the input current can be truly restored. The measured current range can range from milliamps to tens of thousands of amperes. The coil part of the flexible current clamp does not have any exposed metal conductors, non-contact measurement, safe and fast; it is small in size, light in weight, beautiful in appearance, soft and flexible, suitable for narrow environments and places with dense wiring; high measurement accuracy, strong reliability, The response frequency is wide, and users can customize the coil length according to their needs. The meter also has the functions of peak hold, data hold, data storage, etc. It is easy to use and is an essential tool for electrician safety testing. |
