Baur Viola VLF Tester Repair
The Baur Viola is a compact, lightweight VLF cable test set — a portable 0.1 Hz withstand tester for medium-voltage cable, built for crews who need to carry it to the work. Its faults are the HV output-stage, test-port, and battery faults typical of these portable HV sets.
June Company repairs and calibrates the Baur Viola for field cable-testing crews.
Common Viola problems we fix
- Test-port replacement — the HV output connection takes wear and flashover damage, replaced for safe output.
- Measurement-module recalibration — voltage/leakage metering drift, recalibrated.
- Display repair — blank or unresponsive display, fixed.
- Firmware updates — applied as needed during service.
- Won’t reach voltage / won’t hold a charge — output-stage and battery service.
FAQs
My Viola needs the port and metering sorted — both doable? Yes. We replace the test port, recalibrate the measurement module, repair the display, and verify full VLF output, returned with a NIST-traceable certificate.
Can you service the battery? Yes — battery and charging service is routine on these portables.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
