Your Trusted Source Meter Calibration Provider
Micro Precision is an ISO/IEC 17025:2017 accredited calibration provider with NIST-traceable reference standards and a network of more than 50 laboratories operating worldwide. Source meters, also called source measure units (SMUs), combine sourcing and measurement functions in one instrument, and even small measurement drift undermines the accuracy of every downstream test result built on those readings.
Micro Precision provides ISO/IEC 17025:2017 accredited source meter and SMU calibration with NIST-traceable standards, supporting aerospace, defense, medical device manufacturing, automotive, and general manufacturing industries. Our global network of more than 50 laboratories delivers consistent, documented calibration results accepted by quality auditors and regulatory bodies across regulated industries worldwide.
Source meter and SMU calibration is one part of Micro Precision’s broader electrical calibration services portfolio. Micro Precision already services specific instruments including the Keithley 2450 and Keithley 2612B, part of our dedicated Keithley instrument calibration services.
Why Source Meter Calibration Matters
Source meter calibration matters because sourcing and measurement accuracy directly affects R&D data integrity, production test yield decisions, and regulatory compliance. A source meter or SMU that drifts out of tolerance produces readings that appear valid but mask device characterization errors, mislead pass/fail testing decisions, and create non-conformance findings during ISO/IEC 17025:2017-based quality audits.
Regulatory frameworks reinforce this requirement directly. ANSI/NCSL Z540.3 requires documented, objective evidence of calibration for measuring and test equipment used in regulated processes, while ISO 10012 establishes measurement management system requirements, including calibration intervals and traceability controls. For quality managers and compliance officers, a valid calibration certificate with clear traceability is not optional.
Procurement officers rely on accredited calibration vendors to reduce sourcing risk and simplify audit preparation, while lab technicians and test engineers depend on accurate source and measurement readings to trust their characterization and production test results. Micro Precision supports both priorities with standard and rush turnaround options and both in-lab and on-site calibration service, backed by ISO/IEC 17025:2017 accreditation.
Ensure Accurate Source Meter Calibration
Accurate source meter calibration requires a structured process that verifies both sourcing and measurement functions against known references and corrects any deviation found. Micro Precision follows a documented calibration workflow for every source meter and SMU received, performed under the controls required by our ISO/IEC 17025:2017 accreditation.
The process for each instrument includes:
- Receipt and inspection — instrument condition, channel count, and source/measure range configuration are verified on arrival
- Performance testing — the source meter is tested against laboratory reference standards traceable to NIST across its sourcing and measurement functions to establish as-found status
- Adjustment — systematic measurement errors are corrected using calibration methods appropriate to the instrument’s type and range configuration
- Post-adjustment verification — measurements confirm the instrument performs within required parameters after calibration
- Documentation — a certificate of calibration is issued, documenting the calibration date, interval, standards used, and as-found and as-left data
- Return — the calibrated source meter is packaged and returned with its certificate of calibration
Standard and rush turnaround options are available for time-critical programs. Contact our team to discuss current lead times and priority scheduling.
Our Calibration Options
Micro Precision offers both in-lab and on-site source meter calibration to match your equipment configuration, testing environment, and program timeline. Choosing between the two options depends primarily on whether the source meter is a benchtop R&D instrument or a unit integrated into an automated test system.
In-Lab Calibration
Ship your source meter to one of our accredited laboratories for full-capability calibration under controlled conditions. In-lab service supports the complete range of calibration documentation options, including ISO/IEC 17025:2017 accredited certificates with NIST-traceable measurement results.
On-Site Calibration
For source meters and SMUs integrated into automated test systems or production racks that cannot be removed from service, Micro Precision sends qualified calibration technicians directly to your facility. On-site calibration reduces downtime, eliminates shipping risk, and keeps production and test operations running while delivering the same documentation options available for in-lab service.
Rush Turnaround
Standard and rush turnaround options are available for both in-lab and on-site service. Contact our team to discuss current lead times and priority scheduling.

Frequently Asked Questions
A source measure unit (SMU) is a test instrument that combines a precision power supply, a digital multimeter, and an electronic load in one device, allowing it to source and measure voltage or current simultaneously. Source meters and SMUs are used together across R&D, production test, and semiconductor characterization applications.
Yes. “Source meter” and “source measure unit” describe the same instrument category and are used interchangeably across the industry, including by Keithley, the manufacturer most associated with the SourceMeter product line. Micro Precision calibrates source meters and SMUs under one accredited scope regardless of which term is used.
Micro Precision recommends an annual calibration interval for most source meters and SMUs, consistent with common quality program requirements and ANSI/NCSL Z540.3 guidance for measuring and test equipment. Instruments used in high-precision production test or characterization work may warrant a shorter interval based on usage and risk.
NIST traceability confirms a source meter’s measurement results connect through an unbroken chain to national standards held by the National Institute of Standards and Technology. ISO/IEC 17025:2017 accreditation goes further, adding independent, third-party verification that the calibrating laboratory’s processes, equipment, and personnel reliably produce those traceable results. Many quality programs specifically require accredited documentation.
Source meter and SMU calibration cost depends on the instrument model, number of source and measure ranges, and service level selected. Micro Precision does not publish flat-rate pricing because scope varies by manufacturer and configuration. Contact our team for a calibration quote specific to your source meter inventory.
Every Micro Precision source meter calibration includes a certificate of calibration documenting the calibration date, defined interval, reference standards used, and as-found and as-left measurement data. The certificate confirms NIST traceability and, where applicable, ISO/IEC 17025:2017 accreditation scope, giving quality managers the audit trail their compliance programs require.
Yes. Micro Precision provides on-site calibration for Keithley source meters and other SMUs integrated into automated test systems where shipping is impractical. Qualified technicians travel to your facility with NIST-traceable reference standards and complete the same documented calibration process used in our accredited laboratories, including certificate issuance.
