Product Overview

The Keithley 6514 Electrometer combines flexible interfacing capabilities with current sensitivity, charge measurement capabilities, resolution, and speed that are equal or superior to our earlier electrometers. The Keithley 6514 Electrometer's built-in IEEE-488, RS-232, and digital I/O interfaces make it simple to configure fully automated, high speed systems for low-level testing. The 5½-digit Keithley 6514 Electrometer is designed for applications that demand fast, yet precise measurements of low currents, voltages from high resistance sources, charges, or high resistances.

Features and Specifications of the Keithley 6514 Programmable Electrometer:

• Applications include measuring currents from light detectors and other sensors, beam experiments, and measuring resistances using a current source
• A built-in constant current source simplifies measuring resistance
• Two analog outputs:
  • 2V output
  • preamp output
  • Both available for recording data with stripchart recorders
• >200TΩ input impedance on voltage measurements
• Charge measurements from 10fC to 20µC
• High speed -- up to 1200 readings/second
• Interfaces readily with switches, computers, and component handlers
• Cancels voltage and current offsets easily
• 5 1/2 digit
• Built-in IEEE-488, RS-232, and digital I/O interfaces
