Description

Hioki ST5541 Leak Current Tester Repair

The Hioki ST5541 is a leakage current tester — it measures the leakage current of electrical products against safety-standard measuring networks (simulating the human body) to verify compliance for medical and electrical equipment. As a precision leakage-measurement instrument, its faults concentrate in the measurement front-end, the measuring-network circuitry, and the input/range protection.

June Company repairs and calibrates the Hioki ST5541 for product-safety and QC teams.

Common Hioki ST5541 problems we fix

  • Leakage-current measurement out of spec — measurement front-end drift that skews your pass/fail, recalibrated against standards.
  • Measuring-network faults — the standard measuring-network (MD) circuitry not weighting the measurement correctly, repaired.
  • Input / range faults — a range not reading, often after an over-range event, repaired.
  • Input-protection faults — repaired after a miswire.
  • Display or interface faults.

FAQs

My ST5541 leakage readings are off — fixable? Yes. Measurement and network faults are repairable, then the tester is recalibrated so leakage measurements and pass/fail are accurate, with a NIST-traceable certificate.

Is the measuring network verified? Yes — the measuring-network response 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.

Shipping & Returns

Packing your equipment. You are responsible for packaging equipment adequately for transit. We strongly recommend the original manufacturer’s case, or double-boxing with at least two inches of shock-absorbing material on all six sides. We return your equipment in the packaging it arrived in, so please send it in packaging that will survive the return trip as well. If your packaging is damaged or inadequate for the return, we will substitute suitable packaging and may charge the cost of materials.

Insurance. Equipment is not insured by June Company while in transit. We strongly recommend insuring your shipment for its full replacement value.

Risk of loss. Risk of loss remains with you until your equipment is received at our facility, and transfers back to you when your repaired unit is delivered to the carrier (F.O.B. shipping point). June Company is not responsible for equipment lost, delayed, misdelivered, or damaged in transit, in either direction.

Return label. A prepaid and preprinted return shipping label should be included with your shipment. If one is not included, we will provide one.

Transit damage. Damage occurring in transit is the responsibility of the carrier. It is not a warranty defect and is not covered by the 90-day repair warranty. Any claim must be filed by you with the carrier; we will supply photographs and documentation to support it at no charge.
