Chroma 19311 Cell Surge Tester Repair and Calibration
The Chroma 19311 is a battery-cell insulation and surge (Hi-Pot) tester — it tests battery cells and packs for insulation integrity and withstand, applying controlled voltage and detecting breakdown or leakage on cells during production. It combines an HV/surge source with sensitive leakage detection tuned for cells, so faults span both the source and the measurement side.
June Company repairs and calibrates the Chroma 19311 for battery-manufacturing and cell-test teams.
Common Chroma 19311 problems we fix
- HV/surge output won’t reach setpoint — output-stage failure, rebuilt so it applies the rated test voltage to cells.
- Leakage / breakdown detection off — the sensitive measurement your pass/fail depends on, recalibrated against standards.
- False fails or misses — detection-threshold or front-end faults, corrected.
- Won’t communicate / automation faults — the interface to line control, restored.
- Display or control faults.
FAQs
My 19311 throws false fails on cells — fixable? Yes. Detection-threshold and front-end faults are repairable, then recalibrated so cell pass/fail is accurate, with a NIST-traceable certificate.
Is the test voltage verified? Yes — output and leakage measurement are checked against our standards.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
