Description

Hioki MR8740 Memory Recorder Repair

The Hioki MR8740 Memory Recorder is a bench oscilloscope. Its accuracy depends on the analog front-end ahead of the digitizer – attenuators, relays and amplifiers that are switched every time a technician changes a range, and which therefore wear in a way the digital section never does.

June Company’s certified technicians repair the Hioki MR8740 Memory Recorder for electronics engineers, R&D laboratories, service departments, and production test teams. Every instrument is repaired at component level and verified against reference standards before it ships back, with the measured results documented.

Common Hioki MR8740 Memory Recorder problems we fix

Trigger unstable or not arming.
Display, backlight or touchscreen faults.
Cooling fan or thermal shutdown.
Internal power supply faults.
GPIB, LAN, USB or remote-control faults – which breaks automated test sequences while the instrument still works from the front panel.
Channel dead, noisy, or inaccurate – input front-end damage, usually from an over-range input, repaired at component level.
Attenuator relays intermittent – these click on every range change and eventually stop making reliable contact, which shows as an amplitude error on some ranges and not others.
Vertical amplitude accuracy drifted.
Timebase accuracy out of specification.

FAQs

Do you service instruments past manufacturer support? Yes. Much of what we repair is out of support, which is exactly where component-level work earns its keep.

What if it is not economical to repair? We tell you in the quote. The evaluation is free if you approve the repair. If you decline, the evaluation fee is $245.

Every repair carries a 90-day parts-and-labor warranty, with a firm quote before any work begins. 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.
