Tettex 2226A Micro-ohmmeter Repair Services
The Tettex Instruments 2226A is a critical instrument used by substation maintenance crews, switchgear technicians, transformer service teams, and rail maintenance crews. When this equipment fails or drifts out of specification, June Company delivers expert repair and NIST-traceable calibration to restore full operational accuracy.
About the Tettex Instruments 2226A
As a low resistance ohmmeter instrument, the Tettex Instruments 2226A is designed for demanding applications. Specifically, low resistance ohmmeters (DLROs) measure very small resistances in circuit breaker contacts, bus bar joints, cable splices, and motor windings using 4-wire Kelvin measurement. Accurate and reliable performance is essential — measurement drift or component failure can cause costly errors, compliance issues, and project delays.
Common Low Resistance Ohmmeter Issues We Repair
Our repair process addresses the root cause of every issue:
- Current source drift: diagnosed through systematic testing and resolved with component-level repair
- Voltage sense amplifier degradation: identified during our multi-point inspection and corrected to restore specification performance
- Kelvin probe connector wear: addressed with OEM-grade components and verified against traceable standards
- Display faults: repaired by technicians experienced with Tettex Instruments instrumentation
- Battery pack degradation: resolved through targeted diagnostics and precision repair techniques
Calibration and Performance Verification
After repair, we perform comprehensive calibration across all operational modes. For the Tettex Instruments 2226A, this includes verification of contact resistance and DLRO performance, with results documented on a NIST-traceable calibration certificate.
