Description
Tettex 2840 Dielectric Analyzer Repair
The Tettex 2840 is a high-voltage dielectric analyzer — it applies controlled high voltage and measures leakage current and dielectric behavior to test insulation and dielectric materials. It combines a regulated HV source with precision leakage-current measurement, so its faults span the HV regulation and the measurement circuitry.
June Company repairs and calibrates the Tettex 2840 for HV test labs and insulation-diagnostics teams.
Common Tettex 2840 problems we fix
- Voltage regulation drift — output wandering off setpoint, a common 2840 fault, repaired for a stable, accurate HV output.
- Leakage-current measurement errors — drift in the measurement that the test depends on, recalibrated against standards.
- HV output low or won’t come up — source-section degradation, restored.
- Interface or download faults.
- Display or control faults.
FAQs
My leakage readings are off — fixable? Yes. Leakage-measurement drift is repairable and recalibrated, then verified so your dielectric results are accurate, with a NIST-traceable certificate.
Is the HV regulation corrected too? Yes — output stability and accuracy are restored and verified.
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.
