Fluke power quality analysers help locate, predict, prevent and troubleshoot problems in power distribution systems and include many features to capture details to pinpoint problems quickly and safely. Troubleshooting is fast with on-screen display of trends and captured events, even while background recording continues.

Complete three-phase troubleshooting tool: measures voltage, current, frequency, power, unbalance and flicker, harmonics, inter harmonics, power consumption (Energy) and inrush
AutoTrend: Every displayed reading is automatically and continuously recorded without having to set up threshold levels or interval times
Displays trends in voltage, current, frequency, power, harmonics or flicker on all three phases plus neutral
Analyse the trends using the cursors and zoom function while background recording continues
System-Monitor: gives immediate insight into power system’s quality. Checks conformity to limits specified in EN50160 or to user defined limits. The overview is shown on a single screen, with colour-coded bars clearly indicating which parameters fall outside the limits
Inrush mode for troubleshooting nuisance circuit breaker tripping
Four channels: simultaneously measures voltage and current on all three phases and neutral
Meets EN61010-1 600 V CAT IV, 1000 V CAT III safety standard required for measurements at the service entrance.
Rugged, handheld instrument operates for more than 7 hours on included rechargeable NiMH battery pack
Complies with IEC 61000-4-30 measurement standards.
Stored measurements can be transferred to a PC to view graphs and generate reports with FlukeView software with OC4USB interface adaptor / cable (supplied)
