CLEVELAND, Ohio - April 27, 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 Resistance 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 measurement accuracy:
o Measurement circuit
o Leakage currents and guarding
o Noise and source resistance
o Zero drift
o Generated currents
o Overload protection
o AC interference and damping
o Using a coulombmeter to measure low current
Topics addressed in the e-handbook related to high resistance measurements include:
o Constant-voltage method
o Constant-current method
o Guarding
o Settling time
In addition to these topics, the e-handbook provides two measurement applications 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, electrometers, and ohmmeters, are included. In addition, links are provided to a variety of webinars, white papers, and application notes relevant to each topic area.
