1、Outline
QYZ-G07 Transformer field calibrator is to adapt to the scene in harsh environments and designed to facilitate the work of an intelligent transformer tester, the instrument on the measurement principle used some new techniques and algorithms, so that the test data is more stable and accurate; use large-screen LCD touch screen, makes the operation more convenient, fast, and efficient; use WIFI wireless network to communicate with the computer, automatic measurement, automatic judgment errors and automatically generates reports.
2、 Technical Features
1）Wide measurement range, the measured transformer can be accurately measured from 0.001 to 2，Resolution 10-7。
2）Using electronic principles, combined with advanced DSP technology, the higher the sampling frequency, test data is more stable and more realistic.
3）Using an 8-inch large-screen touch-screen LCD display, full Chinese prompts, easy to operate, can store and browse a large number of real-time measurement data.
4）Provided procedures measured, the measurement of non-regulation, and freedom measure multiple measurement functions, provide direct measurement of the value of each point of the entire value, tolerance tips.
5）Can be connected directly to the computer machine, through a dedicated control software can be automatically controlled via WIFI and wired networks, automatic testing, automatic judgment, automatic output reports.
