Keithley 617
Programmable Electrometer
Description
The Programmable Electrometer is our latest and most advanced electrometer.
It is a sensitive, versatile, 41/2 digit, 7 function instrument which includes a bipolar 100V voltage source, a decade current source, IEEE-488 interface, and outstanding low current accuracy specifications.
It is a highly sensitive instrument designed to measure voltage, current, charge, and resistance.
Two forms of resistance measurements are included in the standard configuration a constant current method, and a constant voltage method that uses a built in voltage source for greater sensitivity.
The measuring range is between 10uV and 200V for voltage measurements, 0.1fA and 20mA in the current mode, 0.1ohms and 200Gohms (up to 10^16 ohm using the built in voltage source), and 10fC and 20nC in the coulombs mode.
The very high input impedance and extremely low input offset current allow accurate measurement in situations where many other instruments would have detrimental effects on the circuit being measured.
