Xtester-Portable Transformer Turn Ratio Tester

Important Note

  If the instrument is not in use, please turn off the power in time.

      If the instrument is not used for a long time, please charge and discharge regularly. Batteries should be charged and discharged at least once a month.

      It is strictly forbidden to use power shortage, which will severely shorten the battery life and even make the battery scrap. When the instrument is short of power, the power supply should be switched off and charged immediately. Avoid battery failure due to excessive battery discharge time.

      Charging lamp: the charging lamp on the charger is bright red during charging and bright green after charging.

Users must not disassemble the instrument and replace the battery without authorization. When the instrument or battery fails, please return to the factory.


Hand-held transformer turn ratio tester is an innovative product with compact size, hand-held operation, more portable and easy to carry.

      Products are mainly applied to change than group test transformer, PT and CT polarity test, test speed, high accuracy.

 Packaging Content

  After receiving the packing box, open the packing box and check if there is any damage. If the freight packing box is damaged or the liner material is indented, please inform the freight company or our salesman immediately.

       Please check if you have received the following items in the product package:

 Functional Characteristics

  •  Lithium battery power supply or 100-240V AC power supply is self-adaptive. After one charge, more than 100 transformers can be continuously tested in the ratio group. The test process is simple and convenient.

  •  It has the function of blind measurement, that is, to perform variable ratio and group test when there is no connection between high and low voltage.

  •  Based on the test of conventional transformer, Z-type transformer and PT sample, the polarity test function of CT variable ratio is added, and the application field is wider

  •  Wide range and high accuracy, the variable ratio measurement range can reach 10,000, and the test accuracy can be guaranteed 0.3% when the maximum value is 10,000.

  •  It has perfect protection functions such as reverse connection protection and output short circuit protection.

  • 5.6-inch super industrial high-brightness color LCD screen, still visible under strong sunlight.

  • equipped with external printer, facilitate data printing

  • It can be stored locally and on USB memory.
