Meatest M631 Resistance Decade Box Repair
The Meatest M631 is a programmable resistance decade box — it provides precise, selectable resistance values (switched via internal precision resistors and relays) used as a reference to calibrate and test ohmmeters, bridges, and resistance-measuring instruments. As a precision reference, its faults concentrate in the precision resistor network, the switching relays, and the control interface.
June Company repairs and calibrates the Meatest M631 for calibration labs and metrology teams.
Common Meatest M631 problems we fix
- Resistance value out of spec — drift in the precision resistor network, recalibrated against standards.
- Switching / relay faults — a decade or step not selecting correctly, the relays repaired.
- Open or intermittent value — connection or relay-contact faults, repaired.
- Control / programming faults — the remote interface, restored.
- Terminal or display faults.
FAQs
My M631 outputs the wrong resistance — fixable? Yes. Resistor-network and switching faults are repairable, then the box is recalibrated so its resistance values are accurate and the instruments you calibrate from it are trustworthy, with a NIST-traceable certificate.
Are all decades verified? Yes — each step 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.
