High precision measurement: Advanced phase-locked loop technology and synchronous sampling AC signal processing technology are adopted to ensure the accuracy of measurement data. The voltage and current measurement accuracy reaches 0.2 level, and the power and impedance measurement accuracy performs well at different power factors.
Built in adjustable power supply: The tester is equipped with an adjustable power output, which can complete the measurement of all winding pairs without the need for an external voltage regulator, greatly facilitating on-site testing work.
Wide range measurement: Supports wide range voltage and current measurement, with voltage measurement range from AC 3V to 300V and current measurement range from AC 0.2A to 20A, meeting the testing needs of different types and specifications of transformers.
Single phase and three-phase testing: Supports short-circuit impedance measurement for single-phase and three-phase transformers. For three-phase transformers, all winding pairs can be measured with just one wiring, resulting in high testing efficiency.
Intelligent judgment and prompt: The tester has intelligent judgment function. When there is an abnormality in the test results, it will prompt the user to retest all winding pairs to ensure the reliability of the test results.
Data storage and export: Built in non power down memory, can store measurement data for a long time, and supports USB test data export, making it convenient for users to manage and further analyze data.
Convenient operation: Adopting a fully Chinese menu and operation prompts, the interface is friendly and intuitive, and the operation is simple and fast, even first-time users can quickly get started.
Multiple protection functions: Equipped with comprehensive protection functions such as overvoltage protection, overcurrent protection, etc., to ensure the safety and reliability of the testing process. At the same time, the tester also supports external CT and PT to further expand the measurement range and meet more testing needs.
