The analysis portfolio is bigger than even the DCA55, offering enhanced message display and intelligent component identification. This superb instrument displays incredibly detailed information in scrollable pages. The Atlas combines an impressive analysis portfolio with unequaled ease of use. Connect your component any way round and let the Atlas do the rest. It will measure the gain of transistors, the threshold voltage of MOSFETs, and semiconductor voltage drops. This product has additional component testing capability than the DCA55, but also offers full curve tracking which is downloadable to a MS excel via a USB cable. This allow more in depth analysis of components than was possible before. Supplied fully assembled, tested and aligned with a factory warranty this is an indispensable piece of test equipment for a system designer or product technician, we use one in our store all the time to measure transistors and diodes.
