We understand the role voltmeters play in your electrical testing and quality programs, and we provide the accreditation and traceability your quality management system requires.
Why Voltmeter Calibration Matters
Voltmeter calibration matters because discrepancies in voltage readings lead to hazardous electrical malfunctions and costly equipment damage. Regular voltmeter calibration, consistent with ANSI/NCSL Z540.3, verifies that voltage measurements remain accurate and traceable, reducing the risk of electrical failures and unplanned downtime.
Proactive maintenance and timely repairs prevent reduced data accuracy and operational disruptions across the industries that depend on voltmeters for electrical safety. Micro Precision’s ISO/IEC 17025:2017 accredited calibration process addresses these risks directly, and our technicians provide repair services as part of our commitment to accuracy, promptly addressing issues that arise with your calibrated equipment.
Ensure Accurate Voltmeter Calibration
Micro Precision ensures accurate voltmeter calibration through a structured process: receiving your voltmeter, testing it against a NIST-traceable reference standard, adjusting it as needed, issuing a calibration certificate, and returning the instrument ready for use. Every voltmeter calibration is backed by our ISO/IEC 17025:2017 accreditation and NIST-traceable measurement standards.
Our skilled technicians are knowledgeable about the nuances of a variety of voltmeter models and brands, enabling specialized calibration solutions suited to your specific needs. Repair services are also available as part of our commitment to accuracy, addressing issues that arise with your calibrated equipment. Customers managing a broader range of electrical test equipment can also review Micro Precision’s digital multimeter calibration and oscilloscope calibration services.
Our Calibration Options
Micro Precision offers voltmeter calibration through in-lab service at our accredited calibration facilities and onsite calibration service at your location, depending on your equipment’s configuration and operational needs. Both options provide the same ISO/IEC 17025:2017 accredited, NIST-traceable calibration, with faster turnaround options available for time-sensitive schedules.
In-lab calibration suits voltmeters that can be shipped to one of our calibration labs, while onsite calibration supports fixed installations and equipment that is impractical to relocate.
Voltmeter Types We Calibrate
Micro Precision calibrates a variety of analog and digital voltmeters used across electrical testing, industrial, and laboratory environments, including instruments from Fluke, Keysight, Keithley, BK Precision, Agilent, Anritsu, and Amprobe, among others. Equipment we service includes handheld and bench digital voltmeters, analog panel voltmeters, and precision laboratory voltmeters from these and other manufacturers.

Frequently Asked Questions
Voltmeter calibration is the process of comparing a voltmeter’s displayed voltage readings against a known, NIST-traceable reference standard and adjusting the instrument as needed so its measurements remain accurate. Micro Precision performs voltmeter calibration under ISO/IEC 17025:2017 accreditation and documents results with a certificate of calibration for every voltmeter tested.
Voltmeter calibration frequency depends on usage, environment, and manufacturer recommendations, with many calibration programs using an annual interval as a general baseline. Voltmeters used in high-precision applications or subjected to frequent handling require more frequent calibration. Micro Precision’s technicians determine an appropriate calibration schedule based on your equipment and industry requirements.
Voltmeter calibration cost varies based on the instrument type, calibration service level selected, and whether in-lab or onsite service is required. Because pricing depends on these factors, Micro Precision provides project-specific quotes rather than a flat rate. Request a calibration quote to receive accurate pricing for your voltmeter model and service level.
Calibrating a voltmeter involves applying a known reference voltage from a traceable standard, comparing it to the voltmeter’s displayed reading, and documenting any deviation. Technicians adjust the voltmeter when it falls outside acceptable limits and verify the result before issuing a calibration certificate. Micro Precision performs this process in ISO/IEC 17025:2017 accredited labs using NIST-traceable references.
ISO 17025 voltmeter calibration refers to voltmeter calibration performed under ISO/IEC 17025:2017 accreditation, the international standard for the competence of testing and calibration laboratories. Micro Precision holds ISO/IEC 17025:2017 accreditation across its lab network and provides NIST-traceable voltmeter calibration that meets this standard, supporting audit readiness and regulatory compliance.
Voltmeter calibration is important because inaccurate voltage readings lead to electrical malfunctions, safety hazards, and costly equipment damage. Regular calibration, consistent with ANSI/NCSL Z540.3, verifies that a voltmeter’s measurements remain accurate and traceable. Micro Precision’s accredited calibration services maintain measurement accuracy and compliance across your electrical test equipment.
A voltmeter needs calibration when its calibration due date has passed, when it produces readings that appear inconsistent with a known reference, or after any drop, repair, or environmental exposure that affects accuracy. Following the calibration interval on your certificate of calibration is the most reliable way to know when your voltmeter is due for recalibration.
