1、High resolution 7 inch high brightness full color PLC touch screen（distinguishability 800×480），voltage、electricity、time、Status information and prompt information are all displayed on the same screen，Clear reading、anschauung；
2、WindowsXP，Simple and clear operation, suitable for many applications；
3、High precision touch screen operation, all functions can be set by touch, improve the safety and reliability of the product；
4、All-digital calibration method, eliminating the old potentiometer adjustment, field use is extremely convenient, precision is easy to control (this function with password protection)；
5、Directly set the test transformer ratio (this function with password protection)，In connection with different voltage levels of the tester, the application of flexible, truly achieve a control box can be used with multiple transformers；
6、Status reminder function, Chinese guided operation, even in the absence of instructions can be skillfully controlled；
7、During the test, there is a display on the screen to remind operators to pay attention to safety；
8、Sound and light alarm function can be used when the test is abnormal；
9、When the automatic timing function is automatically controlled, when the voltage rises to the set value, the device will automatically start the timing. When the timing time is up, the test result will be displayed, and the device will automatically return to zero；
10、Manual control mode, this mode is similar to the traditional electric voltage rise and fall mode, rise and fall by the button control, the device automatically judge the upper and lower limit, overvoltage protection；
11、Intelligent control of voltage boost speed, when the voltage reaches 90% of the target voltage, the voltage boost speed will automatically slow down to ensure accurate reaching of the target voltage；
12、Step-up speed can be set, and the step-up speed can be adjusted according to different test transformer ratio, so as to achieve more reasonable effect；
13、Using hardware and software anti-interference technology, stable performance, strong anti-interference；
14、With its own printing function, it can print test data, test date and other contents quickly；
15、USB Offload function，The saved test data can be exported to USB disk for long-term backup；
