The ‘s feedback ammeter design minimizes voltage offsets in the input circuitry, which can affect current kithley accuracy.

This leakage current represents an error current. Instrument have no missing parts and overall very clean. Model voltage reference.

In a similar manner, offset currents can also be cancelled.

Equipment used during restoration project: A, May Model Datasheet Brochure As with all recent Keithley gear, schematics or detailed construction information is not available.

Providing the finest test equipment solutions since 1992

Low Voltage Burden The ‘s feedback ammeter design minimizes voltage keihtley in the input circuitry, which can affect current measurement accuracy. The lowers this terminal voltage still further-to the level of the voltage noise-by canceling out the small offset voltage that remains. Model Instruction Manual, no schematics, Rev. A normal-mode rejection ratio NMRR of 60dB allows making accurate low current measurements, even in the presence of line frequency induced currents, which is a common concern in production keithleu environments.

While the can be easily operated manually using the front panel controls, it can also be externally controlled for automated test applications. Economical Component Testing Once, electrometers were simply considered too slow to keep up with the high throughput that production test applications demand.

If you willing to contribute or add your experience regarding any test instruments or provide any extra information, such as firmware dumps, internal photographs, you can do so following these simple instructions Manuals Here are available manuals from KI so far.

For example, like those instruments, a built-in constant current source simplifies measuring resistance.

Applications include measuring currents from light detectors and other sensors, beam experiments, and measuring resistances using a keithely source. The Keithley Programmable Electrometer combines flexible interfacing capabilities with current sensitivity, charge measurement capabilities, resolution, and speed that are equal or superior to our earlier electrometers.

Once, electrometers were simply considered too slow to keep up with the high throughput that production test applications demand. If you willing to contribute or add your experience regarding any test instruments or provide any extra information, such as firmware dumps, internal photographs, you can do so following these simple instructions. They usually have voltage, current, resistance and charge measurement functionality, just like usual DMMbut can do these measurements with minimal loading on the circuit under test.

Voltage Burden and Measurement Error Electrometers provide current measurement with lower terminal voltage than is possible when making DMM measurements.

The is designed for fast, sensitive measurements, providing speeds up to readings per second with fast integration or 17 measurements per second with 60Hz line-cycle integration. All information posted here is hosted just for education purposes and provided AS IS.
