The AT512 is a high-precision, wide-range, high-performance microprocessor-controlled precision resistance Tester. It can measure the resistance of 0.1μΩ~110MΩ and display a maximum of 200,000 numbers. The maximum test speed is 150 times/sec and the accuracy is up to 0.01%. In 2010, the new upgraded version has a maximum output current of 3A and higher stability. The highly integrated design and scientific structural design of AMMG Instrument make the chassis of AT512 not only compact and lightweight, but also strong and shock-resistant, making it suitable for both laboratory and measurement room use, as well as field operation. Its wide range of tests can be adapted to a wide range of different requirements.
