3. Direct measurement can be performed within the allowable measurement range of the instrument; when exceeding the measurement range, an external voltage transformer and current transformer can be connected.
4. The instrument has high measurement accuracy and good repeatability. Measurement results can be directly stored, and the instrument has a built-in non-volatile memory that can store measurement results for a long time and can be reviewed at any time.
5. It has an RS-232 interface, which can be connected to an external printer or communicate with a computer. The test wiring is simple and clear, with color-coded connections for convenience and speed.
6. Non-volatile calendar and clock functions

Main Features
The transformer loss parameter tester is a dedicated device for measuring transformer loss parameters in power transformers. The instrument uses digital synchronous sampling technology to accurately measure the effective values of parameters such as voltage, current, power, power factor, and frequency of three-phase electrical equipment.
It mainly tests the no-load loss (iron loss) and load loss (copper loss) of transformers.
Wide linear range, good reading repeatability, and stable performance.
Ensures accurate measurement of power factor from 0.0001 to 1.000, especially suitable for testing low power factor loads.
Convenient latching function ensures the simultaneity of measurement data and ease of operation.
