Keithley 6514 Programmable Electrometer
The Keithley 6514 is a programmable electrometer that provides charge measurements from 10fC to 20µC and a reading rate of up to 1200 readings per second. Model 6514 was built for applications that demand fast and precise measurements of low currents, voltages from high resistance sources and charges. Keithley model 6514 can be manually operated using its front panel controls or externally controlled with the unit's built-in IEEE-488, RS-4232 and digital I/O interfaces that make it simple to configure fully automated, high speed systems for low-level testing. The 6514's feedback ammeter design minimizes voltage offsets in the input circuitry, which can affect current measurement accuracy.
