Tettex 2226A Micro-ohmmeter Repair
The Tettex 2226A is a micro-ohmmeter — it sources DC current and uses a 4-wire Kelvin measurement to read very low resistances like contact joints, bus connections, and winding resistances down to the micro-ohm range. Its character is high-current sourcing plus precision low-resistance measurement, so faults concentrate in the current source and the Kelvin measurement path.
June Company repairs and calibrates the Tettex 2226A for substation and testing crews measuring low-resistance connections.
Common Tettex 2226A problems we fix
- Won’t reach test current — current-source degradation, repaired so it sources full current for stable readings.
- Readings erratic or won’t settle — Kelvin lead/connector wear or measurement drift, the usual cause, repaired and recalibrated.
- Micro-ohm accuracy out of spec — measurement-circuit drift, recalibrated against standards.
- Display or interface faults.
- Power or battery faults.
FAQs
My low-resistance readings jump around — fixable? Yes. That usually traces to the Kelvin connections or measurement circuit; we repair and recalibrate so 4-wire readings are stable and accurate, with a NIST-traceable certificate.
Is the micro-ohm accuracy certified? Yes — verified against our reference standards.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
Shipping & Returns
Packing your equipment. You are responsible for packaging equipment adequately for transit. We strongly recommend the original manufacturer’s case, or double-boxing with at least two inches of shock-absorbing material on all six sides. We return your equipment in the packaging it arrived in, so please send it in packaging that will survive the return trip as well. If your packaging is damaged or inadequate for the return, we will substitute suitable packaging and may charge the cost of materials.
Insurance. Equipment is not insured by June Company while in transit. We strongly recommend insuring your shipment for its full replacement value.
Risk of loss. Risk of loss remains with you until your equipment is received at our facility, and transfers back to you when your repaired unit is delivered to the carrier (F.O.B. shipping point). June Company is not responsible for equipment lost, delayed, misdelivered, or damaged in transit, in either direction.
Return label. A prepaid and preprinted return shipping label should be included with your shipment. If one is not included, we will provide one.
Transit damage. Damage occurring in transit is the responsibility of the carrier. It is not a warranty defect and is not covered by the 90-day repair warranty. Any claim must be filed by you with the carrier; we will supply photographs and documentation to support it at no charge.
