VEER make Automatic Transformer Turn Ratio Meter - VTRM measures no-load Turn Ratio of transformer means Ratio of High Voltage Winding to Low Voltage Winding of Transformer. You can read Turns Ratio directly from front LCD display. It also measures and display % Deviation, Excitation Current. VTRM has inbuilt Data Storage Memory to store 200 Test Results. It can transfer all test results to Computer using dedicated Software.
