Keithley 617 Opts: no option
The Model 617 Programmable Electrometer 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. The 617 can measure resistances or generate I-V curves using either of two measurement techniques. Using the 1nA to 100??A decade current source, a known constant current is forced through the unknown resistance. The developed voltage is measured with a high input impedance voltmeter, and the resistance or voltage is displayed and transmitted over the IEEE bus. Alternatively, the 617#039;s programmable voltage source is applied across the unknown and the resulting current is detected by the 617#039;s sensitive current circuitry. Current may be displayed directly, or resistances as high as 101612 can be directly measured. The 617 can calculate and...Option: no option
The Keithley 617 Programmable Electrometer 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 of the Model 617 is between 10µV and 200V for voltage measurements, 0.1fA and 20mA in the current mode, 0.1Ω and 200GΩ (up to 1016Ω 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. A 4½ digit display and standard IEEE-488 interface give the user easy access to instrument data.
