— WHAT IS RESISTANCE METER CALIBRATION —
Think of a quality lab that relies on a resistance meter 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.
Resistance Meter calibration means comparing its readings against a NABL-traceable certified reference standard at multiple test points, recording the deviations, adjusting where possible, and issuing an NABL certificate — accepted by ISO 9001, IATF 16949, and all quality auditors.
Compare readings against a NABL-traceable reference standard across the full measurement range.
Adjust or document deviations so your instrument reads within accepted tolerance.
Issue a NABL-accredited certificate (CC-2480) with full traceability documentation.
— INSTRUMENTS COVERED —

— OUR PROCESS —
Resistance meter received. Measurement method (2-wire/4-wire/Kelvin), resistance ranges, and test current documented.
NABL-traceable precision reference resistors connected in 2-wire or 4-wire Kelvin configuration per instrument design.
Resistance calibrated at 5 setpoints per range spanning decades: 1 Ω, 10 Ω, 100 Ω, 1 kΩ, 10 kΩ etc. 4-terminal method used where applicable.
For LCR meters: resistance function verified at each available test frequency (100 Hz through 1 MHz). Inductance and capacitance verified separately.
Error at each calibration point documented. Expanded uncertainty (k=2) per GUM. Results compared to manufacturer specification.
NABL CC-2480 certificate with resistance data, deviations, uncertainty (k=2), IEC 61010 traceability.

NABL Accreditation Standard
Prism holds NABL CC-2480 under ISO/IEC 17025:2017. Resistance and LCR meter certificates accepted by ISO 9001, 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.
