Fluke 190-504/S ScopeMeter Repair

The Fluke 190-504/S is a rugged, isolated handheld ScopeMeter — a 500 MHz four-channel portable scope (190 II series; the /S adds the SCC accessory kit), the top of the line, with independently floating, isolated inputs for demanding field troubleshooting on power, motor-drive, and electronic systems. As a field-carried instrument, its faults concentrate in the isolated input front-ends, the display, and the battery/power section.

FAQs

My 190-504/S has a weak channel or lost bandwidth — fixable? Yes. Isolated-input and response faults are repairable, then the channels are recalibrated so measurements and full bandwidth are restored, with a NIST-traceable certificate.

Are all four channels recalibrated? Yes — each channel is checked against our standards.

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