A channel on my 190-504 is off — fixable? Yes. Isolated-input and trigger faults are repairable, then each of the four channels is recalibrated so measurements are accurate, with a NIST-traceable certificate.
Are the inputs recalibrated? Yes — each of the four channels is checked against our standards.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or request service.

Our Fluke scopemeter would not take a charge, therefore died, but the battery was good. Checked everything I could and ended up sending in for evaluation. They gave me a detailed explanation of the repair and did a great job repairing and certifying the scopemeter.
