The KDHG-518C variable frequency transformer characteristic tester only requires simple digital settings: setting the rated parameters of the transformer. The instrument will automatically record data throughout the entire process and calculate and display the polarity and volt ampere characteristic curves of the transformation ratio, eliminating the tedious labor of changing wires, manually adjusting voltage, manually recording, organizing, and drawing curves.

with large capacity memory, can store 2000 groups of test data, data power off never lost; 
single machine integration, light weight, only 8.2Kg, easy to carry, easy to flow test;
automatic inflection point calculation function, test data screening and printing function, with date/time function.
