Status: Current Production. We repair and calibrate all of them.
Common HVI ALT Series Problems We Fix
- Won’t reach test voltage / output low or unstable — HV multiplier stack failure
- Leakage current reading drifting or inaccurate — critical for pass/fail decisions
- HV cable or connector arcing / insulation breakdown
- Voltage won’t regulate or hold setpoint
- Safety interlock won’t clear / won’t allow test to start
- Control circuit faults or aging
- Won’t power on

Frequently Asked Questions
How much does HVI ALT Series repair cost?
Repairs start with a flat evaluation fee that’s credited toward your repair cost. After we diagnose the instrument, you get a firm quote before any work begins — no surprises.
How long does the repair take?
Most HVI ALT repairs are finished within 5–10 business days of arrival, with expedited turnaround available if you need it back fast.
My tester won’t reach full test voltage — can you fix it?
Yes. HV multiplier stack failures that cause low, unstable, or missing output are one of the most common faults on these testers, and they’re fully restorable to rated voltage.
My leakage current readings look off — can you recalibrate it?
Yes, and this is the measurement that matters most. The leakage current reading is what determines whether an aerial lift passes or fails, so we recalibrate the metering circuit against our reference standards and document the results on a NIST-traceable certificate.
Will the repaired tester still meet ANSI A92.2 and OSHA requirements?
Yes. We verify output voltage accuracy, metering accuracy, and the safety functions so your tester continues to support dielectric testing under ANSI A92.2 and OSHA 1910.67, with documented results on a certificate.
The safety interlock won’t clear and the test won’t start — is that repairable?
Yes. Safety interlock relay faults that block a test from starting are a routine repair, restored so the instrument’s protective functions work as intended.
Can you repair arcing HV cables or connectors?
Yes. High-voltage cable and connector insulation degradation that causes arcing or breakdown is repairable, restored for safe, reliable high-voltage testing.
What if my exact model isn’t listed?
We service every HVI ALT Series configuration. If your model isn’t in the table, pick the closest match or email us — the process is the same.
Who uses the HVI ALT Series?
Electric utilities, bucket truck fleet maintenance shops, aerial lift testing contractors, tree service companies, and OSHA compliance testers rely on the ALT Series to verify the dielectric integrity of insulated booms and upper controls.
