Multimeter Calibration: Protecting Your Operations From Measurement Drift

Call Now for Immediate Service

We provide multimeter calibration for organizations where inaccurate electrical measurements create regulatory risk, production delays, or safety hazards. When your quality team depends on precise voltage, current, and resistance readings to release product or clear equipment for use, measurement drift isn’t just inconvenient—it’s a compliance gap waiting to be found.

Our laboratory provides both NIST traceable and ISO 17025 accredited multimeter calibration services. We test your equipment against reference standards that meet federal and international standards, then provide the detailed certificates your auditors expect to see. Send equipment to our climate-controlled lab for testing, or we can accommodate on-site service when facility constraints require it.

After 50 years calibrating electrical test equipment, we understand what’s actually at stake: passing audits, maintaining production schedules, and proving your measurements are defensible.

Why Choose Allometrics for Multimeter Calibration

ISO 17025 Accreditation You Can Verify

Our laboratory holds A2LA ISO 17025 accreditation – the internationally recognized benchmark for calibration laboratory competence. [1] [2] This means an independent assessor has verified our technical capabilities, measurement uncertainty calculations, and quality management system.

NIST Traceability on Every Certificate

Your calibration certificates document the complete measurement chain – from your multimeter to NIST traceable standards. This traceability withstands regulatory scrutiny. [3]

50+ Years Calibrating Electrical Test Equipment

Since 1976, we’ve calibrated measurement instruments for organizations that face audits, manage tight production tolerances, and answer to regulatory bodies. Therefore, we understand the documentation requirements, turnaround pressures, and accuracy demands you face.

Allometrics Multimeter Calibration Process

What is Multimeter Calibration?

Multimeter calibration compares your instrument’s measurements against known reference standards traceable to NIST. We apply precise input values across your meter’s measurement ranges – voltage, current, resistance, frequency – and record how your instrument responds. If readings fall outside specified tolerances, we document the deviation and can repair on approval. You receive certificates showing measurement performance before and after any adjustments.

Benefits of Regular Multimeter Calibration

Regular calibration catches measurement drift before it affects your operations. Scheduled testing identifies accuracy changes while equipment is still usable, preventing failed audits, questionable product releases, and production delays from emergency calibration needs. Documented calibration history demonstrates measurement control when regulators or customers audit your quality systems.

Risks of Neglecting Multimeter Calibration

Uncalibrated multimeters create compliance gaps that auditors will find. Equipment drifts out of tolerance while still displaying normal-looking readings, leaving you unable to prove measurements were valid when you released product or cleared equipment for use. Missing calibration records often trigger expanded audit scrutiny of your entire quality system – corrective actions that cost far more than preventive calibration. Worse, uncalibrated meters lead to costly decisions: scrapping good product, removing functional equipment from service, or releasing defective product because your test equipment said it passed.

Laboratory Service for Accurate Results

Send your multimeters to our laboratory for calibration against NIST traceable reference standards. Standard turnaround is 7-10 business days for most instruments, with expedited 48-hour service available when audit deadlines or production schedules demand faster turnaround.

Field Service When You Need It

We can perform on-site calibration when equipment size, quantity, or facility requirements make shipping impractical. Our technicians bring calibrated reference standards to your location and provide the same documentation quality as laboratory service.

Nationwide Coverage

We serve regulated industries across the United States. Whether you operate a single facility or manage calibration programs across multiple sites, we provide consistent service and documentation that satisfies your quality system requirements.

FAQ: Answers to Your Multimeter Calibration Questions

What’s the process for calibrating a multimeter?

The calibration process compares your multimeter’s measurements against reference standards that trace back to NIST. We apply precise input values across all your meter’s measurement ranges—including voltage, current, resistance, and frequency—then record how your instrument responds to each test point. If any readings fall outside the specified tolerances, we document those deviations and can perform repairs with your approval. You’ll receive detailed certificates showing your equipment’s measurement performance both before and after any adjustments we make.

What are the consequences if I skip multimeter calibration?

When you skip calibration, your multimeters drift out of tolerance while still displaying readings that look perfectly normal. This creates compliance gaps that auditors discover during reviews, leaving you unable to prove your measurements were valid when you released products or cleared equipment for operation. We’ve seen missing calibration records trigger expanded audit scrutiny of entire quality systems, resulting in corrective actions that cost far more than preventive calibration would have. Uncalibrated meters also lead to expensive mistakes—you might scrap acceptable product, remove functional equipment from service unnecessarily, or worse, release defective product because your test equipment incorrectly indicated it passed specifications.

Do I need to calibrate my multimeter?

You need to calibrate your multimeter if you work in a regulated industry where measurement accuracy affects product quality, worker safety, or regulatory compliance. Your multimeter measurements directly influence decisions about releasing products, clearing equipment for use, and demonstrating compliance during audits. Without documented calibration, you can’t prove your measurements are defensible when regulators or customers review your quality systems. We calibrate multimeters for organizations that must document measurement traceability—if that describes your operation, then yes, calibration is necessary for your equipment.
