After many complications and delays, mostly caused by almost two years of the Covid-19 pandemic, here we managed to arrive and launch these two new test device concepts, developed from scratch by Bob Parker in Australia and marketed by EVB meters in Portugal. They are an evolution, very demarcated, from all previous versions where many improvements have been introduced, from the power supply, microprocessing and testing process, all this effort goes towards offering repair technicians an even more evolved and precise tool from previous versions and with a improved performance at all levels, all at a very attractive price.
