The Keithley 2400 is a standard 20 W SourceMeter instrument that tightly couples a highly stable DC power source with a true instrument-grade 5½-digit multimeter. Operating as a compact, single-channel DC parametric tester, it functions as a voltage source, current source, voltage meter, current meter, and ohmmeter. With 4-quadrant operation, it is capable of sourcing and sinking power, making it ideal for testing components like diodes, resistors, active circuit protection devices, and portable battery-powered electronics.
