Description

Keithley 6400 Picoammeter Repair

The Keithley 6400 Picoammeter is a multi-product calibrator – it sources voltage, current, resistance and other quantities to calibrate a bench of instruments. Because each capability runs through its own output stage, a fault normally removes one function and leaves the rest working perfectly.

The Keithley 6400 Picoammeter is repaired at June Company by technicians who work on this class of instrument daily, for calibration laboratories, instrument workshops, and in-house metrology programs. Every instrument is repaired at component level and verified against reference standards before it ships back, with the measured results documented.

Common Keithley 6400 Picoammeter problems we fix

Readings drifted out of tolerance – corrected and verified against reference standards.
Current output stage failure.
Resistance or capacitance synthesis faults.
Range switching and relay 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.
Display, keypad or front-panel faults.
One function failing while the others work – the characteristic pattern, and the reason a single failed output rarely means a failed instrument.

FAQs

Do you verify every function or just the reported one? Every function. Checking only the reported fault is how a second drifting output leaves undetected.

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.
