- Laboratory bench testing and field troubleshooting of AC-powered equipment
Compatibility & Integration As a discontinued product, the 403B may present sourcing constraints. Original documentation and spare components availability should be verified prior to procurement for critical measurement applications. Direct integration with modern digital acquisition systems requires external interface solutions.
Agilent / Keysight 403B — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Agilent / Keysight 403B. Calibration covers DC voltage accuracy at all ranges, AC voltage (True RMS) accuracy at 50 Hz, 1 kHz, and 10 kHz, DC current accuracy, resistance accuracy at all decade ranges, frequency accuracy, and diode test voltage. Fluke 87V and 289 also include capacitance and temperature calibration.. All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.
Common Agilent / Keysight 403B faults: blown input fuse, worn input jacks, display segment failure, relay contact wear on bench DMMs. Common faults include worn input jacks (banana socket contact wear on the mA and COM terminals), blown input fuses (especially the 440 mA HRC fuse), and display segment failures. Keithley 2000/2001/2002 bench DMMs commonly develop relay contact wear affecting resistance accuracy after extended service.
