Xtester-ETCR3800A Lightning Protection Component Tester,SPD tester,Surge Protective Device(SPD)tester for Metal Oxide Varistors (MOV)、Voltage Dependent Resistor (VDR)，（GDT）（gas discharge tube)
INTRODUCTION
Xtester-ETCR3800 series Intelligent Lightning Protection Component Tester is used to measure the performance parameter of various metal oxide varistor (MOV) and gas discharge tubes (GDT), The instrument has unique functions of high voltage short circuit protection, overcurrent protection, professional parameter setting function, high voltage limit setting, boost speed setting, qualified range setting, qualified judgment and screening, automatic range adjustment and so on.Also with single test mode and continuous test mode function, especially suitable for batch component testing.Among them, ETCR3800B also has the functions of insulation resistance, absorption ratio and polarization index. The instrument output voltage up to 3000V, starting action voltage U1mA measuring range: 50 ~ 3000V, the leakage current measuring range: 0 ~ 1000uA, DC breakdown voltage measuring range 50 ~ 3000V, repeat testing with good stability, accurate and reliable, with excellent test stability and anti-interference ability.The instrument is widely used to test the performance parameters of over voltage protection elements such as lightning arrester, lightning arrester, surge protector, varistor, cermet discharge tube, vacuum lightning arrester, etc. Xtester-ETCR3800 series Intelligent Lightning Protection Component Tester adopt with touch color screen interface, control and operation with one key, Users do not have to memorize the operation method, click "HELP" key on the screen to pop up the operation method, effectively guiding the user to operate the instrument. The meter adopts with large capacity rechargeable lithium battery, and has the function of automatic test data storage, which can store 3000 groups of test data, has the data upload function with USB interface, convenient for users to check the historical test records. The instrument has shockproof, dustproof, moisture-proof structure, the whole machine is beautiful and durable, adapt to the harsh working environment, is weather lightning protection, electric power, communications, mechanical and electrical installation and maintenance, lightning protection components manufacturers, as well as industrial enterprise departments commonly necessary instruments. |
