Product Overview
CT92-5A/CT92-10A dual power DC resistance tester is designed specifically for temperature rise measurement of three core and five column large transformers. It has fast charging and measurement speed, and can meet the time requirements of transformer temperature rise testing. It has dual channel measurement, real-time sampling, and printing output, making temperature rise testing no longer a problem.
Functional characteristics
1.The instrument has a high output current and voltage.
2.Dual channel measurement, simultaneously measuring two resistance values.
3.Equipped with complete protection circuits and strong reliability.
4.Horizontal structure, convenient for on-site operation in the transformer factory.
5.Equipped with audio discharge alarm, clear discharge indication, reducing misoperation.
6.Any temperature conversion function made of copper and aluminum materials, touch to input any winding temperature and conversion temperature.
7.The instrument has RS232 communication and USB interface, which is used for computer communication and USB data storage. It comes with a panel type micro printer and can print measurement results in Chinese.
8.Adopting a 7-inch high-definition touch screen.
9.The instrument comes with a perpetual calendar clock and power down storage, which can store 200 sets of data and can be viewed at any time.
