■ Functional features
▲ Wider measuring range, faster test speed.
▲ Support transformer neutral heterofrequency signal injection method and compensation capacitor bank neutral heterofrequency signal injection method.
▲ Industrial-grade color LCD screen, resolution 320×240 dot matrix, readable under strong light.
▲ Human-computer interaction interface is more friendly:
Displays prompts and help for important operations and parameter Settings.
The measurement results and related parameters are displayed and printed in more detail for users to analyze in the future.
When PT connection mode is selected, wiring schematic diagrams of all PT connection modes are displayed for users to identify the site
PT connection mode and test line connection position.
▲ The status bar at the top of the screen displays the real-time insertion status of the USB disk. When operating the unconnected device, the corresponding unconnected prompt message will be displayed.
▲ Real-time measurement and display of zero sequence 3U0 voltage value, easy for users to judge the working state of the system; In addition, if the zero sequence 3U0 voltage is found to be too high in the measurement engineering, the measurement process can be stopped automatically.
▲ With multiple zero sequence 3U0 overvoltage protection circuit, the output end of the tester can withstand AC100V,50HZ voltage without damage.
▲ Built-in full digital frequency conversion inverter power supply, with accurate output frequency, adjustable output current, high output efficiency, small heat, small volume, light weight, long time stable operation and other characteristics.
▲ With output short circuit protection function.
▲ With real-time clock, can display the current time and date in real time; Measurement results include measurement date and time.
▲ Measurement data storage is divided into local storage and U disk storage, the local storage can store 150 measurement data, and the local storage can be transferred to the U disk; The U disk stores data in Word format, which can be edited and printed directly on the computer.
▲ Thermal printer printing function, fast, silent.
▲ Small size, light weight, easy to carry.
