6514

The Keithley 6514 Electrometer combines flexible interfacing capabilities with current sensitivity, charge measurement capabilities, resolution, and speed that are equal to or superior to earlier electrometers. The 6514’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 Keithley 5½-digit 6514 is designed for applications that demand fast, yet precise measurements of low currents, voltages from high resistance sources, charges, or high resistances.

The 6514’s exceptional measurement performance comes at an affordable price. While its cost is comparable with that of many high-end DMMs, the 6514 offers far greater current sensitivity and significantly lower voltage burden (as low as 20µV) than other instruments can provide

R&D on a Budget

The Keithley 6514 offers the flexibility and sensitivity needed for a wide array of experiments, providing better data far faster than older electrometer designs. Applications include measuring currents from light detectors and other sensors, beam experiments, and measuring resistances using a current source. In addition to use by researchers in areas such as physics, optics, and materials science, the 6514’s affordable price makes it an attractive alternative to high-end DMMs for low current measurement applications, such as testing resistance and leakage current in switches, relays, and other components. 

The 6514 builds on the features and capabilities of the Keithley electrometers that preceded it. For example, like those instruments, a built-in constant current source simplifies measuring resistance .

Two analogue outputs—a 2V output and a preamp output—are available for recording data with stripchart recorders
