Product Overview:
It is a multifunctional field test instrument specially designed for testing transformers: volt-ampere characteristics, transformation ratio, polarity, error curves, calculating knee point, and secondary side loop inspection, etc. During the test, only need to set the test voltage and current values, the device can automatically boost voltage/current, and quickly display the volt-ampere characteristic curve or transformation ratio, polarity and other test results of the transformer, supporting data storage and on-site printing. It not only saves tedious labor such as manual voltage adjustment, manual recording, and curve drawing, but also can upload test data to a computer via USB interface for editing, saving, or printing. Simple and convenient operation, improving work efficiency, it is a high cost-performance high-tech product.
