Fluke 52120A Transconductance Amplifier Repair

The Fluke 52120A is a transconductance amplifier — it works with a multi-product calibrator to source very high AC/DC currents (to thousands of amps, with coil multipliers) for calibrating clamp meters, current transformers, and high-current shunts. Its precision lives in the high-current output stages and the reference circuitry, which is where service and calibration focus.

FlukeMeterRepair.com repairs and calibrates the Fluke 52120A for calibration labs and instrument repair centers.

Common Fluke 52120A problems we fix

High-current output drift — the sourced current out of spec, repaired and recalibrated against standards.
Output-stage faults — a current stage not driving or distorting, repaired.
Protection / thermal shutdowns — the amplifier tripping protection under high-current load, diagnosed and repaired.
Interface faults — won’t link with the host calibrator, repaired.
Power-supply faults.

FAQs

My 52120A high-current output is off — fixable? Yes. Output-stage and reference faults are repairable, then the amplifier is recalibrated against our standards so its current output is accurate, with a NIST-traceable certificate.

Is the output verified? Yes — checked against our standards (send the host calibrator if relevant).

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