Fluke 5790B AC Measurement Standard Repair

Description

Fluke 5790B AC Measurement Standard Repair

The Fluke 5790B is an AC measurement standard — a metrology-grade thermal-transfer-based instrument that measures AC voltage with very high accuracy to characterize AC sources and transfer AC voltage standards in calibration labs. As a precision standard, its faults concentrate in the input/thermal-transfer front-end, the internal reference, and the measurement electronics.

FlukeMeterRepair.com repairs and calibrates the Fluke 5790B for calibration labs and metrology teams.

Common Fluke 5790B problems we fix

• Output-amplifier / front-end drift — the input or transfer front-end drifting so AC measurements are off, recalibrated against standards.
• Reference drift — the internal reference drifting, which compromises every measurement it makes, recalibrated.
• Input-range faults — a range not measuring correctly, repaired.
• A function dead — input or measurement faults, repaired.
• Communication or display faults.

FAQs

My 5790B AC measurements drifted — fixable? Yes. Front-end and reference faults are repairable, then the standard is recalibrated so its AC measurements are accurate and the sources you characterize from it are trustworthy, with a NIST-traceable certificate.

Is the reference verified? Yes — checked against our reference standards.

Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or request service.
