Low Level Measurements is intended as a practical guide to making precision
measurements of low level DC signals. It is useful both as a reference
handbook and as an aid to understanding low level phenomena
observed in the lab. Keithley’s Applications Engineering staff, who
led the effort that created this Fifth Edition, is available to talk about
the material in the book or other measurement challenges.
The book provides a comprehensive overview of the theoretical
and practical considerations involved in measuring low currents, high
resistances, low voltages, and low resistances.
High impedance measurements are the most complex and least
understood measurement type. This book describes many common
sources of errors and ways to minimize them in order to make successful
high impedance measurements.
Low voltage and low resistance signals pose their own set of measurement
challenges. The book discusses these considerations in depth,
as well as practical measurement methods and applications. It also
discusses design characteristics of the growing variety of low level
measurement instruments, including electrometers, picoammeters,
nanovoltmeters, micro-ohmmeters, SourceMeters, and Source-
Measure Units.
