Yokogawa WT333 Power Meter Repair and Calibration
The Yokogawa WT333 is a three-phase digital power meter (WT300 series) — it measures voltage, current, power, power factor, and harmonics for energy and efficiency testing on single- and three-phase equipment. As a precision measurement instrument, its faults are measurement-accuracy, current-input, and interface faults rather than power-output faults.
June Company repairs and calibrates the Yokogawa WT333 for energy-efficiency and product-test teams.
Common Yokogawa WT333 problems we fix
- Power/voltage/current readings out of spec — measurement-circuit drift, recalibrated against standards.
- Current-input faults — a current element/input damaged (often by overload), repaired.
- Power-factor / harmonic measurement off — the analysis circuitry, restored.
- Won’t communicate — interface faults to a PC or logger.
- Display or control faults.
FAQs
My WT333 power readings drifted — fixable? Yes. Measurement-circuit drift is repairable and recalibrated, then verified so voltage, current, power, and PF read accurately across phases, with a NIST-traceable certificate.
Are the current inputs verified? Yes — each element 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.
