The Fluke 1942 is a fixed-system power quality recorder for three-phase installations in industrial and commercial facilities. It captures voltage sags, swells, waveform faults, and all power parameters simultaneously across nine input channels—four voltage and five current—without requiring manual threshold configuration. Full Disclosure Technology records every detected change in measurements, ensuring no power quality event goes unobserved. The instrument operates in five modes: Recorder, Meter, Monitor, Scope, and Analyzer.
