Keithley Publishes E-Handbook on Precision Low Current, High Resistance Measurements
Cleveland, Ohio, 27 April 2011 * * * Keithley Instruments, Inc., a world leader in advanced electrical test instruments and systems, has published an informative e handbook titled “Making Precision Low Current and High Re-sistance Measurements.” A free copy can be downloaded from Keithley’s website at http://www.keithley.com/pr/088.
The e-handbook covers several topics crucial to ensuring low current measure-ment accuracy:
• Measurement circuit
• Leakage currents and guarding
• Noise and source resistance
• Zero drift
• Generated currents
• Overload protection
• AC interference and damping
• Using a coulombmeter to measure low current
Topics addressed in the e-handbook related to high resistance measurements include:
• Constant-voltage method
• Constant-current method
• Guarding
• Settling time
In addition to these topics, the e-handbook provides two measurement applica-tions examples: avalanche photodiode reverse bias current measurements and voltage coefficient testing of high ohmic value resistors. A useful glossary of low-level measurement terminology and a guide to selecting instruments suitable for low current and high resistance measurements, such as ammeters, electrome-ters, and ohmmeters, are included. In addition, links are provided to a variety of webinars, white papers, and application notes relevant to each topic area.
