High precision and wide range: With high-precision measurement capability, the variable ratio measurement range can reach 10000, and the testing accuracy can still guarantee 0.3% at the highest value of 10000, meeting the testing needs of various types of transformers.
Blind testing function: Without prior knowledge of the high and low voltage connection methods of the transformer, the transformation ratio and group can be accurately measured, greatly facilitating on-site testing work.
Multi functional testing: In addition to conventional transformer ratio group testing, it also supports PT and CT ratio polarity testing, with a wide range of applications.
Lithium battery power supply: It adopts lithium battery power supply or 220V AC power supply adaptive design, and can continuously perform over 100 transformer ratio group tests on one charge, which is very suitable for on-site use.
Intelligent power management: The instrument has intelligent power management function, which automatically dims the LCD backlight to save power when not operated for a long time. At the same time, it has low battery charging prompt and over discharge protection function.
Convenient operation: Equipped with a large high-resolution LCD screen and a fully Chinese graphical user interface, the operation is simple and intuitive, supporting multiple testing modes and parameter settings.
Data storage and printing: Equipped with a thermal printer, it supports local storage and USB storage, making it convenient for users to save and print data.
Complete protection: It has complete protection functions such as reverse connection protection and output short circuit protection to ensure the safety and reliability of the testing process.
