Description

Keithley 6517A electrometer / Keithley 2000 multimeter are used for real time DC measurements (electrical resistance or current), being fully computer controlled. Keithley 2000 is used for lower resistance values (up to 100 MΩ), whilst Keithley 6517A is used for larger resistance values (up to hundreds of TΩ using proper shielding setups).
