Fluke 190-104/S ScopeMeter Repair
The Fluke 190-104/S is a rugged, isolated handheld ScopeMeter — a 100 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. As a field-carried instrument, its faults concentrate in the isolated input front-ends, the display, and the battery/power section.

Our Fluke 190-104 stopped powering up, tried a new charger, then purchased a new battery with no success. Sent our Fluke scopemeter in for evaluation and JT was very on top of correspondence both vie phone and email. Very impressed attention to detail. The Fluke scopemeter was repaired, calibrated to ISO-17025 and returned within a week.
