Fluke 190-204-III ScopeMeter Repair
The Fluke 190-204-III is a four-channel 200 MHz portable ScopeMeter — a rugged, isolated handheld oscilloscope built for field work in industrial and electrical environments, combining scope and meter functions with battery operation. As a field-carried instrument, its faults concentrate in the isolated input front-ends, the display, and the battery/power section.
June Company repairs and calibrates the Fluke 190-204-III for industrial electricians and field-service technicians.
Common Fluke 190-204-III problems we fix

FAQs
A channel got over-ranged and reads wrong — fixable? Yes. Isolated front-end damage is repairable, then the channel is recalibrated so vertical accuracy and bandwidth are restored, with a NIST-traceable certificate.
Can you replace the battery too? Yes — battery and power service is routine.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
