— WHAT IS UNIVERSAL CALIBRATOR CALIBRATION —
Think of a quality lab that relies on an universal calibrator for daily measurements. If it has drifted even slightly from its true value, every reading becomes unreliable — leading to defective products, failed audits, or safety risks. Regular calibration is the only way to confirm your instrument is telling the truth.
Universal Calibrator calibrationmeans comparing its output against a NABL-traceable certified reference standard at multiple setpoints, recording the deviations, adjusting where possible, and issuing an NABL certificate — accepted by ISO 9001, IATF 16949, and all quality auditors.
Compare output against a NABL-traceable reference standard across all functions and ranges.
Adjust or document deviations so output reads within accepted tolerance.
Issue a NABL-accredited certificate (CC-2480) with full traceability documentation.

— OUR PROCESS —
Universal calibrator received. All active output functions (V DC, V AC, I DC, I AC, Ω, Hz, TC types, RTD types) inventoried against calibration scope.
NABL-traceable primary measurement standards connected to measure/verify each calibrator output: precision voltmeter, ammeter, resistance standard, frequency counter, mV source.
Each output function calibrated at 5 setpoints per range. DC and AC voltage, DC and AC current, resistance, frequency, TC mV, and RTD resistance all calibrated in sequence.
TC mV output at 5 temperature points per TC type compared to IEC 60584 mV table. RTD resistance at 5 points compared to IEC 60751 resistance table.
Error at each setpoint for all functions. Expanded uncertainty (k=2) per GUM. Certificate lists results for each function with traceability chain.
NABL CC-2480 certificate listing all calibrated output functions with data, deviations, uncertainty (k=2), and IEC 61010 / IEC 60584 / IEC 60751 traceability.

Prism holds NABL CC-2480 under ISO/IEC 17025:2017. Universal calibrator certificates accepted as top-level reference instruments by ISO 9001, pharma, IATF 16949, and all process industry QMS audit bodies.
— NON-NABL CALIBRATION —
For routine maintenance, bulk calibration, or internal QC checks where a full NABL certificate is not mandatory — Prism offers cost-effective non-NABL calibration using the same NABL-traceable reference standards and trained engineers.
All non-NABL work uses NABL-certified reference standards — readings are still reliable and defensible.
Without full NABL documentation, instruments return faster — ideal for urgent production schedules.
Non-NABL calibration costs less — practical for large batches or routine periodic checks.
Available at your facility or at our Vatva lab — same quality, more flexibility.
— AREAS WE SERVICE —
Courier pick-up and delivery. 1-day turnaround for most universal calibrators.
Why Choose Prism
Since 2004, every NABL universal calibrator certificate from Prism has been accepted by ISO 9001 and IATF 16949 auditors — no rejections.
