Description

Hioki 3930 High Voltage Scanner Repair

The Hioki 3930 is a high-voltage scanner — a switching/multiplexer unit that routes a hipot or insulation tester’s high voltage and measurement to many test points, automating multi-point safety testing on multi-conductor products. As an HV switching unit, its faults concentrate in the high-voltage relays/matrix, the channel routing, and the control interface.

June Company repairs and calibrates the Hioki 3930 for production safety-test and QC teams.

Common Hioki 3930 problems we fix

Channel / relay faults — a scan channel not routing the HV/measurement correctly, the HV relays repaired so every channel switches.
HV-routing leakage or breakdown — insulation faults in the switching matrix from HV stress, repaired.
Control-interface faults — won’t sequence or communicate with the tester, restored.
Intermittent channel — relay-contact wear, repaired.
Connection or power faults.

FAQs

One of my scanner channels won’t connect — fixable? Yes. HV-relay and routing faults are repairable, then every channel is verified with the tester so multi-point testing is reliable, with documented results.

Do you test it with a hipot tester? Yes — the scanner is verified as part of the working test system.

Every repair includes calibration verification and a 90-day parts-and-labor warranty. Email us or submit a service request.
