ETCR EM3800B Lightning Protection Component Tester, also known as lightning protection component testing instrument, SPD on-site tester, varistor tester and surge protector tester, which is used for measuring performance parameters of various varistor (MOV), gas discharge tube (GDT), and surge protector (SPD), also has insulation resistance(Mohm), polarization index (PI), dielectric absorption ratio(DAR) test function,etc. The tester not only has unique functions such as high-voltage short circuit protection, overcurrent protection, professional level parameter setting, high-voltage limit setting, boost speed setting, qualified range setting, qualified judgment screening, automatic range adjustment, etc., but also has single piece testing mode and continuous testing mode function, which is especially suitable for batch component testing. The tester is widely used for testing the performance parameter of overvoltage protection component such as lightning arrester, surge protector, varistor, metal ceramic discharge tube, vacuum lightning arrester, etc. It is a commonly used and essential instrument for meteorological lightning protection, power, communication, mechanical and electrical installation and maintenance, lightning protection component manufacturer, and industrial enterprise department.

ETCR EM3800B Lightning Protection Component Tester adopts true-color touch screen with Chinese interface, direct function, one-click measurement, easy and effective to operate. User do not need to laboriously memorize the operation method, click “HELP” on the screen to pop up the operation method, effectively guiding the user to operate the instrument. At the same time, the instrument adopts a large-capacity rechargeable lithium battery, with memory function, can automatically store 3000 sets of test result containing date and time, the touch screen is convenient for user to check historical record, USB data upload and export functions, as well as automatic shutdown, low battery reminder and other functions.
