The Fluke 123 Industrial ScopeMeter combines a dual-channel digital oscilloscope, true-RMS multimeter, and paperless recorder into a single handheld platform for industrial troubleshooting. Technicians diagnose electrical and electromechanical faults in machinery, control systems, and power distribution using Connect-and-View automatic triggering and IntellaSet signal analysis.
