• This state- of- the- art tester offers a new solution for low inductance coil test.

• Its advanced technology enhances a complete waveform and partial discharge observation ability by the resistive voltage divider.
• Its high sampling rate of 100 MHz delivers highly sensitive and precise test.
• The partial discharge amount calculated by the Laplacian method is displayed clearly in a separate sub- window.

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 ne w

solution to the low inductance coil tests.

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- 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 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.

All types of coils can be evaluated by choosing a combination of various test methods: Area Size Comparison, Differential Area

Size Comparison, Flutter Value (Corona Discharge) Detection, and Laplacian Value (Corona Discharge) Detection.

(* The Flutter Value Detection and the Laplacian Value Detection can only be selected alternatively.)

The remote control operation by PC, through the use of peripheral devices like the RS- 232C port and LAN port (optional), can

provide management of master data, test data and results.

With the Centronics printer port, a screen hard copy can be printed easily by an ESC/ P printer with ESC/ P format.

With our thorough research attempts, this high- end tester contains a great design of smaller circuits. Compact and light, the

DWX is suitable for coil testing in limited space like designing or maintenance site, workbench, R& D and quality control fields.

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

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

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

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

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

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

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

Printing of the screen hard copy can be made easily through the Centronics printer port.

Various operations become much easier with the rotary dial and the menu display through the icon button.

The optional Ethernet adaptor enables the DWX’s remote control operation through LAN connection.

The DWX unit is compact, durable and weighs only 10 kg.
