Description
Kingsine KS803 Calibrator Repair
The Kingsine KS803 is a precision calibrator / reference source — it generates accurate reference quantities used to calibrate and verify protection-test and measurement instruments. As a precision reference source, its faults concentrate in the internal reference, the output stages, and the range/function switching.
June Company repairs and calibrates the Kingsine KS803 for calibration labs and protection-test teams.
Common Kingsine KS803 problems we fix
- Output-accuracy / reference drift — the reference or output drifting out of spec, which compromises every cal, recalibrated against standards.
- Stability faults — output unstable over time, repaired.
- A function out of spec — a specific output drifting, repaired and recalibrated.
- Range / function switching faults — the output routing, restored.
- Display, control, or interface faults.
FAQs
My KS803 output drifted — fixable? Yes. Reference and output-stage faults are repairable, then the calibrator is recalibrated so its outputs are accurate and stable, with a NIST-traceable certificate.
Are all functions verified? Yes — each output is 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.
