Product introduction
| MEWOI4850 Transient Suppressor Diode Tester, also called TVS Tester, is specially designed for TVS diode performance index test, and is an industrial-grade tester. It is composed of host computer, LCD liquid crystal display screen, upper computer software, power adapter and so on. Compared with traditional Zener diodes, TVS diodes have the advantages of faster response speed and are widely used in circuit design. Therefore, in order to ensure the performance of the product, it is particularly important to test the performance of each diode shipped from the factory. Among the performance indicators of TVS diodes, the most important indicator is "reverse breakdown voltage". This product is designed for the detection of this indicator. Compared with the traditional measuring instruments, this product has an LCD liquid crystal display function, which is convenient for user operation and test result display. The LCD liquid crystal display part is mainly composed of several parts such as 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; it is compatible with other measuring instruments The hardware design is also different than the power button and other function keys. This instrument uses a rotary switch, which has a longer service life and is more convenient to use than traditional buttons; in terms of power supply, this product is powered by a rechargeable lithium battery. It is easy to carry, and you only need to fully charge it to work in places without electricity. Compared with traditional dry batteries, it is more durable and environmentally friendly. Another highlight is the test result recording function. Each gear can store 1000 test records. Users can view and operate the test results. At the same time, they can use the host computer software equipped by the company to view and operate the test records. Provide test record export function, users can export test records to EXCEL table. In this way, users can view, compare and analyze the test data. |
