Tester Turns Ratio and Transformer Winding Resistance Tester TTR Winding Meter 2 in 1

Tester Turns Ratio and Transformer Winding Resistance Tester TTR Winding Meter 2 in 1

1.With one wiring connection, DC resistance tests, transformation ratio tests. 2.DC resistance test function: For Yn type, Y type and △ type winding, it adopts three-phase automatic testing, and calculates the three-phase unbalance rate; The maximum output current is 20A, which can support the very low resistance tests of the low-voltage coil of distribution transformers. 3.With 7 inch industrial large screen display, fresh and simple display style design, full touch combined with jog dial operation, it creates comfortable and convenient human-computer interaction experience for you. 4.The instrument adopts embedded Linux operating system, which has high safety, smoothness, ease of use, etc. 5.This instrument uses large capacity lithium battery to provide power and has a built-in charger. 1. Power Supply：Built-in lithium battery with capacity of 7.8AH
2. Charging voltage：AC220V
3.Use temperature：-10℃～50℃
4.Relative Temperature：≤90%, non-condensing
