https://www.mktester.com/transformer-test-system/transformer-comprehensive-analyzer/transformer-calibrator.htmlProduct description：Transformer calibrator is a new automatic instrument. We apply advanced electronic technology in the design. By directly decomposing the error signal, it is able to display the percentage, phase error and orthogonal error statistically. It’s quick and energy saving. And it’s especially good for live testing due to its cute dimension and light weight.
