Compatible with transistors (both germanium and silicon), darlingtons, MOSFETs, junction FETs, low-power thyristors and triacs, LEDs, diodes, and diode networks, the DCA55 instantly carries out detailed component analysis, allowing users to quickly access detailed information on connected components.
Incredibly compact and ideal for transportation/storage, the DCA55 includes three coloured test leads for direct connection to a component. The component can be connected any way around and once connected, the user simply presses the test button for instant detailed information about the connected component.
This information is presented in easily scrollable pages and includes information on component type, special component features, component pinout, and measures parameters such as gain, leakage current, gate threshold voltages, voltage drops, and more.

Don't spend a significant period searching through books and articles to find component information; the DCA55 takes the difficulty out of the component analysis, providing instant feedback and detailed information at all times.
