Cleveland, Ohio—July 7, 2009—The Metrology Services organization at Keithley Instruments, Inc. (NYSE: KEI),
a world leader in advanced electrical test instruments and systems, has
expanded the scope of its ISO 17025 accreditation with the American
Association for Laboratory Accreditation (A2LA). Keithley’s accredited
calibrations now include customer-site calibrations that involve DC
voltages from 0 to 200 volts and DC currents from 0 to 1 ampere. This
expanded scope now allows Keithley to offer accredited calibrations of
its Model 4200-SCS Semiconductor Characterization System, which is
capable of measuring and sourcing currents with femtoamp resolution.

Keithley’s
metrology laboratory has been an A2LA-accredited calibration facility
since 2006, when it was first accredited in accordance with the
International Standard ISO/IEC 17025:2005 General Requirements for the
Competence of Testing and Calibration Laboratories. The company’s
German service center was accredited by A2LA in 2007. This
accreditation assures Keithley customers that their instruments are
being calibrated to the highest industry standards, so they can
continue to deliver consistent, quality measurements. Routine
calibrations help prevent unplanned downtime and costly quality
problems.
