   ETCR 3850 transient suppression diode tester, also known as TVS tester, is specially designed for testing the performance of TVS diodes. Among the performance indicators of transient suppression diodes, the most important index is "reverse breakdown voltage". This product is designed for this index detection.

   This product adds LCD liquid crystal display function. The LCD liquid crystal display part is mainly composed of voltage threshold input, qualification judgment, test result display, real-time voltage and current display, measurement record usage, battery power display, test record display and test record operation. The product has the function of recording test results, and 1000 test records can be stored in each gear. users can view and operate the test results, and at the same time, they can use the host computer software equipped by our company to view and operate the test records. it provides users with the function of exporting test records, and users can export test records to EXCEL tables. In this way, users can view, compare and analyze the test data.
