Fluke 190-502/S ScopeMeter Repair
The Fluke 190-502/S is a rugged, isolated handheld ScopeMeter — a 500 MHz two-channel portable scope (190 II series; the /S adds the SCC accessory kit), the highest-bandwidth model in the line, with independently floating, isolated inputs for demanding field troubleshooting. As a field-carried instrument, its faults concentrate in the isolated input front-ends, the display, and the battery/power section.

FAQs
My 190-502/S lost bandwidth or a channel — fixable? Yes. Isolated-input and response faults are repairable, then the channel is recalibrated so measurements and full bandwidth are restored, with a NIST-traceable certificate.
Are the inputs recalibrated? Yes — both channels are checked against our standards.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or request service.
