Keithley 6487/E Digital Multimeter DMM

The Keithley 6487/E is a 5½ Digit Digital Multimeter (DMM) Voltage Source Meter. The meter improves on the measurement capability of previous models with a 500V source voltage. It provides higher accuracy and faster rise times than the 6485, as well as a damping function for use with capacitive devices. With eight current measurement ranges and high speed autoranging, this cost effective instrument can measure currents from 20fA to 20mA, take measurements at speeds up to 1000 readings per second, and source voltage from 200μV to 505V.The 6487 has a 10fA resolution, superior sensitivity, voltage sweeping, and Alternating Voltage resistance measurements making it well suited for characterizing low current devices.
