For engineers and technical managers, maintaining the accuracy and traceability of test and measurement equipment is essential to ensuring product quality and regulatory compliance. One often-overlooked advantage of choosing Tektronix Factory Calibration over third-party providers is the inclusion of instrument adjustments at no additional cost-a benefit that becomes especially critical when dealing with Out-of-Tolerance (OOT) conditions.
Understanding Out-of-Tolerance (OOT) Events
An OOT event occurs when an instrument's measured performance deviates beyond its specified limits. These deviations are typically identified during calibration by comparing the measured value to the specification limit, factoring in measurement uncertainty. For example:
OOT if: ∣ Measured Value−Nominal∣ > Tolerance Limit
OOT events are more common in aging equipment due to component drift, thermal cycling, or mechanical wear. Left unaddressed, they can compromise test integrity, leading to false product validation, field failures, or non-compliance with standards like ISO/IEC 17025 or ANSI/NCSL Z540.3.
What Happens During an Instrument Adjustment?
When Tektronix identifies an OOT condition, our technicians perform factory-authorized instrument adjustments using proprietary procedures and calibration software. This may include:
These adjustments restore the instrument to original design specifications, ensuring continued accuracy and compliance.
Why Tektronix Factory Calibration is Superior
Instrument Adjustments
Unlike third-party providers, Tektronix includes adjustments in the base calibration service. This eliminates the need for additional service orders or fees when an OOT condition is found.
Time Efficiency
Third-party labs often lack the tools or authorization to adjust Tektronix instruments. They must ship the unit back to Tektronix, introducing delays. Tektronix Factory Calibration avoids this by performing adjustments on-site or in-facility, reducing turnaround time.
Cost Savings
Third-party calibration providers can in some cases double your calibration costs due to:
Tektronix includes all of this in a single, flat-rate service.
Expertise and Accreditation
With over 65 years of experience and ISO/IEC 17025-accredited service centers, Tektronix ensures your equipment is calibrated to the highest industry standards using OEM procedures and parts.
