Product description

Features

■ The test speed is as high as 1800 times/s (>10kHz), without relay action time

■ Test level up to 20Vrms

■ The bias voltage is built-in ±40V/±100mA/2A

■ Up to 288 test pins (only TH2840NX)

■ Industry-friendly user experience: Linux bottom layer, built-in help file

■ 10.1 inch 1280×800 capacitive touch screen

■ Graphical pin association setting page, so that wiring is no longer a problem

■ Lk setting does not need to input the leakage inductance pin, which is more intuitive

■ Enhanced balance scanning function, from 5 points to 10 points

■ Range switching adopts electronic switch, fast speed, long life, no noise

■ Optional LCR function

■ Approximately 100M setting file storage space in the machine, and massive U disk setting file storage capacity

■ Provide host computer to support early model file format conversion to ensure compatibility

 

Applications

■ Switching transformer scanning test, comprehensive characteristics analysis.

■ Network transformer scanning test, comprehensive characteristics analysis

■ Discrete passive components (L, R, C) multi-channel scanning test

■ Relay drive line package, contact resistance multi-channel scanning test

■ Multi-channel DC resistance DCR scanning test
