Keithley provides the ExceLINK Excel Add In to interact with the ammeter, but it is not user firendly. Thus, this implementation is designed to have a better UX.
Note Many instrument operations for the instrument depend on the line frequency. This defaults to 50 Hz.
Python and PyQT GUI controllers for a Keithley 6485 / 6487 picoammeter.
