The Fluke 1948 Power Recorder is a nine-channel power quality analyzer engineered to capture voltage, current, harmonics, transients, and power disturbances across industrial and commercial electrical systems. Full Disclosure Technology records all events seen by loads—from 500 ns impulses to long-term outages—without threshold configuration, storing thousands of voltage events and related current waveforms. This enables rapid troubleshooting and preventative maintenance while minimizing equipment downtime.
