Fluke 190-502 ScopeMeter Repair
The Fluke 190-502 is a rugged, isolated handheld ScopeMeter — a 500 MHz two-channel portable scope (190 II series), the highest-bandwidth model in the line, with independently floating, isolated inputs for demanding field troubleshooting on power and electronic systems. As a field-carried instrument, its faults concentrate in the isolated input front-ends, the display, and the battery/power section.
FlukeMeterRepair.com repairs and calibrates the Fluke 190-502 for industrial maintenance and field-service teams.

FAQs
A channel on my 190-502 took a transient — fixable? Yes. Isolated-input damage is 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.

Our Fluke scope meter became intermittent, with readings not stable for our customers reports. We sent in for repair, and they did a great job with the repair and calibration paperwork. Good turnaround time too.
