PRODUCT INTRODUCTION
| Musktool-ETCR3800B intelligent lightning protection component tester, alias: lightning protection component tester, SPD field tester, etc., used to measure the performance parameters of various piezoresistors (MOV) and gas discharge tubes (GDT), the instrument has a unique high voltage Short-circuit protection, over-current protection function, professional-level parameter setting function, high-voltage limit setting, boost speed setting, qualified range setting, qualified judgment screening, automatic range adjustment and other functions. It also has the functions of single test mode and continuous test mode, especially suitable for batch component testing. It also has insulation resistance, absorption ratio, polarization index test functions. The output voltage of the instrument is up to 3000V, the initial action voltage U1mA measurement range: 50-3000V, the leakage current measurement range: 0-1000uA, the DC breakdown voltage measurement range 50-3000V, good repeatability, accuracy and reliability, and excellent test stability performance and anti-jamming capability. The instrument is widely used to test the performance parameters of overvoltage protection components such as lightning arresters, lightning arresters, surge protectors, varistors, metal ceramic discharge tubes, and vacuum arresters. The tester adopts a touch color screen Chinese interface, with direct functions, one-key measurement, and simple and quick operation. The user does not need to 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, and has functions such as data storage, data query, qualification judgment, automatic shutdown, and USB data upload and export. The instrument has a shockproof, dustproof, and moisture-proof structure. The whole machine is beautiful, durable, and adaptable to harsh working environments. It is a necessary instrument commonly used by meteorological lightning protection, electric power, communication, electromechanical installation and maintenance, lightning protection component manufacturers, and industrial enterprise departments. |
