Introduction: Overview of Low Frequency Dielectric Constant Tester GDAT-S is a new impedance analyzer with multiple functions and higher test frequencies. It is small in size, compact and portable, and is easy to use on the shelf. The basic accuracy of this series of instruments is 0.05%, the resolution of the test frequency is 1MHz10mHz, and the 4.3-inch LCD screen is matched with the Chinese and English operation interface, which is convenient and simple to operate. The transformer test function and balance test function are integrated to improve the test efficiency. The instrument provides a wealth of interfaces, which can meet various requirements of automatic sorting test, data transmission and storage.
