With basic accuracy of ±0.07%, loss accuracy of 0.0005, test frequency up to 1MHz, 4.3-inch LCD screen, selectable Chinese-English operation interface, TH2638 series is easy to operate and provide fast and reliable test for ceramic capacitor production. Also, it can test all kinds of capacitors from low value to high value. The results of testing one capacitor for several times are quite stable and accurate, even for lower value capacitors. The tester is compatible with SCPI command set, and configured with manipulator and scanner interface, the scanner interface can scan the open/short/ load error calibration in each channel, 256 channels at most. In low frequency, there is signal level compensation function. When the impedance is very small, the internal resistance in signal source and test cable will cause the voltage on terminal of DUT lower than the set range, then this function will adjust the level to the set range.
