Product Description
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 10 µV and 200 V for voltage measurements, 0.1 fA and 20 mA in the current mode, 0.1 O and 200 GO (up to 10 to the 16th O using the built in voltage source), and 10 fC and 20 nC 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 4.5 digit display and standard IEEE-488 interface give the user easy access to instrument data.
Features and specifications of the Keithley 617 Electrometer include:
4.5 Digit Display: Easy to read front panel LED display \
Autoranging
Digital Calibration
Zero Correct: A front panel zero correct control allows the user to cancel any offsets
Baseline Suppression: One button suppression of a baseline reading is available from the front panel or over the IEEE-488 bus
One Shot Triggering: A front panel control for triggering one shot readings from the front panel is included
Isolated 100 V Voltage Source: A built in 100 V source is isolated from the electrometer section. The voltage source is programmable in 50mV steps
Selectable Guarding: A selectable driven cable guard is included to optimize speed
Standard IEEE-488 Interface
Analog Outputs: Both preamp and 2 V full range analog outputs are included on the rear panel
100-Point Data Store: An internal buffer that can store up to 100 readings is accessible
