Description
Overview
High-Frequency LCR with Test Speed of 50 times/sec – GAOTek is a multi-functional component tester for testing all kinds of electronic components. The most popular 7-in 800×480 color TFT LCD display is adopted; it is more intuitive and more comfortable for users to read test results. It is an impedance meter with high speed, wide test range and 6-bit test resolution.
This can meet the requirements of production line quality assurance, purchase inspection and laboratory measurement. The main test products include microphones, resonators, inductors, ceramic capacitors, liquid crystal displays, reactor diodes, transformers, etc. Interfaces such as Handler, RS232C, USB, GPIB and perfect command system provided by the instrument can help users easily set up a test system.
