  • Notes

  • The Keithley 485 is an auto-ranging digital picoammeter that measures currents in seven decadic ranges from 2 nA to 2 mA full scale.  The least significant digit represents 100 fA (0.1 pA).

    It operates as a feedback (transimpedance) ammeter (i.e. the input burden is constantly low at less than 0.2 mV), has a resulution of 4½ digits (19999) and some rudimentary built-in logging capabilities as well as an optional GPIB interface.
