Với yêu cầu tiên tiến về công nghệ thu nhỏ và tần số cao của các sản phẩm cuộn dây, máy kiểm tra DWX được thiết kế để kiểm tra các cuộn dây khác và cuộn cảm thấp được sử dụng trong các linh kiện điện tử cao cấp. Thông qua việc sử dụng nguồn xung với công tắc tốc độ cao, mạch đầu vào hiệu quả cao và mạch lấy mẫu A/D tốc độ cao, máy kiểm tra DWX có thể cung cấp một giải pháp mới cho các bài kiểm tra cuộn cảm thấp.

This innovative tester offers a news solution for low inductance coil test.

With the advanced requirement of miniaturization and high frequency technology of coil production, the DWX tester is designed to test other coils and low inductance coils used in high-end electronic components. Through the use of impulse power source with high-speed switch, highly efficient input circuit, and high-speed A/D sampling circuit, the DWX tester can offer a new solution to the low inductance coil tests.

Its advanced technology allows a complete waveform and partial discharge observation by the resistive voltage divider.

The high performance voltage divider allows the DWX input circuit of impulse waveform to generate a complete wave pattern without any distortion. At the same time, it also helps improve the partial discharge sensitivity and detection capability
(The DWX’s detection sensitivity is improved compared with that of our DW & DWS series, except for the DW-9505F).

Its high sampling rate of 100 MHz delivers highly sensitive and precise test.

Its high-speed A/D sampling helps to verify the extremely short impulse response of the low inductance coil. At the same time, the 8 kByte sampling, with highly refined data analysis, can precisely capture the subtle difference in the wave patterns.

The partial discharge amount calculated by the Laplacian method is displayed clearly in a separate sub-window.

The employed Laplacian method calculates the partial discharge (PD) generated by high voltage impulse. This PD, abstracted from the voltage wave, visually displays a bar graph in a separate sub-window, offering an easy and comfortable viewing.

The 8.4-inch color TFT LCD screen clearly displays the waveform and is easy to view.

A combination of our proven Area, Dif-Area and Flutter comparison methods can be selected to perform the layer short test.

All types of coils can ve evaluated by choosing a combination of various test mehods: Area Size Comparison, Differential Area Size Comparison, Flutter Value (Corona Discharge) Detection, and Laplacian Value and Laplacian Value (Corona Discharge) Detection. (* The Flutter Value Detection and the Laplacian Value Detection can only be selected alternatively.)

The equipped compact flash memory device offers an unlimited memory of the master data.
