Your Trusted Keithley Calibration Service Provider
Micro Precision provides NIST-traceable, ISO/IEC 17025:2017 accredited calibration and repair services for Keithley digital multimeters, signal generators, power supplies, electrometers, oscilloscopes, switching and control systems, SMUs, and RF power sensors and analyzers. Keithley instruments serve electrical test and measurement applications across aerospace, defense, medical, and manufacturing industries, and Micro Precision’s network of 50+ accredited calibration labs keeps this equipment accurate, traceable, and audit-ready.
Micro Precision’s accredited laboratories and experienced technicians support comprehensive calibration programs for Keithley equipment, issuing documented calibration certificates and providing quality servicing that keeps instruments performing to specification.
Why Keithley Calibration Matters
Keithley electrical test instruments require calibration against recognized standards to maintain measurement accuracy and support compliance audits. ANSI/NCSL Z540.3 governs the calibration program requirements accredited laboratories must follow.
ANSI/NCSL Z540.3 sets the calibration program requirements for accredited laboratories performing electrical test instrument calibration. Micro Precision’s ISO/IEC 17025:2017 accredited labs calibrate Keithley multimeters, SMUs, and other instruments against this standard, with NIST-traceable results documented on every calibration certificate.
Uncalibrated Keithley instruments directly affect measurement integrity: drifted readings can mask out-of-tolerance components, compromise test data, and put quality and safety records at risk. Scheduled calibration protects both compliance and measurement confidence.
Ensure Accurate Keithley Calibration
Micro Precision calibrates Keithley instruments through a defined process: technicians receive and inspect each instrument, test it against NIST-traceable reference standards across its measurement range, adjust it if it is found out of tolerance, issue a calibration certificate, and return the instrument ready for use.
Micro Precision provides both in-lab calibration at accredited facilities and on-site calibration services performed at a customer’s location, with faster turnaround options available, giving quality teams flexibility to schedule Keithley instrument calibration around production needs.

Frequently Asked Questions
Calibration intervals for Keithley instruments depend on usage frequency, environmental conditions, and the tolerance requirements of the application. Industry practice commonly recommends calibration at least annually, with additional calibration after any drop, overload, or observed measurement drift. Micro Precision calibrates Keithley equipment against NIST-traceable standards regardless of the interval a customer selects.
Keithley calibration cost depends on the instrument model, its measurement range, and the service level selected (Traceable, Traceable with Data, or Accredited). Micro Precision provides calibration quotes through its equipment quote request form, so customers receive pricing specific to their Keithley instrument before service begins.
NIST traceable calibration means a measurement result can be linked, through an unbroken chain of comparisons, back to national measurement standards maintained by the National Institute of Standards and Technology. Micro Precision documents this traceability on the calibration certificate issued for every Keithley instrument it services.
Calibrating a Keithley multimeter involves testing it against NIST-traceable reference standards across its voltage, current, and resistance ranges, comparing indicated readings to known values, and adjusting the instrument if it falls out of tolerance. Micro Precision’s technicians perform this process at ISO/IEC 17025:2017 accredited labs and issue a documented calibration certificate.
Calibrating a Keithley SMU involves testing its source and measure functions across specified voltage and current ranges against NIST-traceable reference standards, then adjusting the instrument if readings fall out of tolerance. Micro Precision calibrates Keithley SMUs at the same Traceable, Traceable with Data, or Accredited service levels available for its other instruments.
Calibrating a Keithley instrument requires NIST-traceable reference standards appropriate to the instrument’s measurement type and range, along with documented procedures that meet ANSI/NCSL Z540.3 program requirements. Micro Precision’s ISO/IEC 17025:2017 accredited labs maintain this equipment and issue calibration certificates confirming each Keithley instrument’s performance to specification.
ISO/IEC 17025 does not specify a fixed calibration interval; it requires laboratories to establish intervals based on factors such as instrument stability, usage, and risk of measurement error. Micro Precision works within this framework to calibrate Keithley instruments at intervals appropriate to each customer’s application.
