Description

Fluke PM6681 Counter/Timer Calibration and Repair

The Fluke PM6681 is a high-resolution programmable counter/timer — a benchtop instrument that measures frequency, period, and time interval with very high resolution for electronics, RF, and calibration work. Its accuracy lives in the timebase reference and the counting/measurement circuitry, which is where service and calibration focus.

FlukeMeterRepair.com repairs and calibrates the Fluke PM6681 for calibration labs and electronics shops.

Common Fluke PM6681 problems we fix

Timebase / frequency-reference drift — the reference out of spec, causing inaccurate measurements, recalibrated against standards.
Input / counting-circuit faults — a channel not counting or triggering correctly, repaired.
Communication / interface faults — the GPIB/remote interface not connecting, repaired.
A function dead — a measurement mode failed, repaired.
Display or power faults.

FAQs

My PM6681 measures inaccurately — fixable? Yes. Timebase and input faults are repairable, then the counter is recalibrated against our standards so frequency and interval measurements are accurate, with a NIST-traceable certificate.

Is the timebase verified? Yes — checked against our standards.

Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or request service.
