Fluke 55XX Series Multifunction Calibrators Service (5500A, 5502A, 5520A, 5522A)

ISO 17025 | ilac • MRA | ANAB Accredited

Few labs in North America hold the accreditation and technical depth to calibrate this instrument class – and even fewer deliver within the turnaround time you need. Transcat is one of them.

Why Full-Range Calibration Matters for the Fluke 55XX Series

The 55XX series earns its place on your bench because it does almost everything: DMM calibration, thermocouple and RTD simulation, oscilloscope calibration options, power quality verification.

That breadth is exactly what makes it hard to calibrate correctly. A provider needs standards and expertise across every one of those functions — not just the electrical basics. Send it to a lab that only covers part of the range, and you'll get a certificate with gaps, or a calibrator that comes back only partially verified.

At Transcat, you’ll find the experts who can give you the confidence to maintain your lab’s accuracy weeks before other service providers.

What's Covered in Fluke 55XX Multi-Product Calibrator Calibration

We calibrate the full 55XX multi-product family — 5500A, 5502A, 5520A, and 5522A — across every function it supports:

DC and AC voltage and current, including multi-waveform and harmonic outputs
Resistance and capacitance
Thermocouple and RTD simulation and measurement
Oscilloscope calibration options (600 MHz and 1,100 MHz)
Power quality calibration option, where equipped

Calibration is performed to ISO/IEC 17025:2017 scope with full traceability and documented measurement uncertainty on every certificate.

How Fluke 55XX Series Calibration Accuracy Affects Your Daily Workload

Your 55XX calibrator likely touches more of your daily workload than any other single instrument in the lab:

Measurement confidence

a calibrator this versatile needs to be verified across its full range, not spot-checked on a few functions

Audit readiness

auditors expect to see every active function and option on your calibrator covered by scope

Customer commitments

if your 5522A calibrates handheld meters, scopes, and power quality analyzers, your certificate needs to reflect all of it

Downtime risk

this instrument likely drives a large share of your daily throughput; extended downtime backs up your entire queue

Why Choose Transcat for Fluke 55XX Series Calibration

Complete functional coverage. We calibrate every function and installed option on the 55XX platform, not a subset.

Fluke-specific expertise. Our technicians work with the 55XX family regularly and understand its quirks, options, and common failure points.

Fast, predictable turnaround. We know this calibrator is your daily driver, and we schedule to minimize lab disruption.

One certificate, full scope. No follow-up calibrations needed for options you thought were already covered.

Transcat has spent over 60 years building calibration capability most providers never develop. We operate 22 commercial labs accredited to ISO/IEC 17025:2017 across the United States and Canada, performing over 300,000 accredited calibrations annually.

We're also the only publicly traded commercial calibration provider in North America (NASDAQ: TRNS) - a level of accountability and consistency you won't find at a small independent shop.
