Fluke 190-204/S ScopeMeter Repair
The Fluke 190-204/S is a rugged, isolated handheld ScopeMeter — a 200 MHz four-channel portable scope (190 II series; the /S adds the SCC accessory kit) with independently floating, isolated inputs for industrial and field troubleshooting on power, motor-drive, and electronic systems.
