Status: 5730A Current Production — 5700A / 5720A Discontinued
Overview
The Fluke 5700/5720/5730A Multifunction Calibrators represent the gold standard in high-accuracy electrical calibration. These instruments calibrate digital multimeters up to 8.5 digits with uncertainties measured in parts per million. The 5730A is the current flagship, while the legacy 5700A and 5720A remain in service at national metrology institutes and primary standards laboratories worldwide. The 5725A Amplifier extends current and voltage ranges for demanding workloads.

Common Fluke 5700 Series Failures We Repair
- DC voltage reference drift requiring recalibration against primary standards
- Precision resistance network degradation affecting resistance output accuracy
- AC voltage leveling loop instability on high-frequency outputs
- Current amplifier thermal drift under sustained heavy-current sourcing
- Front panel encoder and display failures on legacy 5700A/5720A units
- Internal relay contact resistance increase from cumulative switching cycles
Our technicians perform component-level diagnostics on every Fluke 5700 Series unit. We don’t just replace boards — we identify and repair the specific failed components, saving you the cost of full module replacements when possible.
Calibration
Every Fluke 5700 Series repair includes NIST-traceable calibration. We verify all primary output and measurement functions against our reference standards and provide a detailed calibration certificate documenting measured performance against the manufacturer’s published specifications.
