brief introduction
High-frequency precision electric bridge is a multi-functional component tester used to test various electronic components. Using the most popular 7-inch 800x480 color TFT LCD screen, users can read the test results more intuitively and more comfortably. It is an impedance meter with high speed, wide test range and 6-bit test resolution.
The instrument meets the requirements of production line quality assurance, purchasing inspection and laboratory measurements. The main test products include microphones, resonators, inductors, ceramic capacitors, liquid crystal displays, varactors, transformers, etc.
The Handler, RS232C, USB, GPIB and other interfaces provided by the instrument, as well as a complete command system, can help users easily build a test system.
