    • Perform dynamic motor analysis by plotting of motor derating factor against load according to NEMA/IEC guidelines
    • Calculate mechanical power and efficiency without the need of mechanical sensors, just connect to the input conductors and you’re ready to go
    • Measure electrical power parameters such as voltage, current, power, apparent power, power factor, harmonic distortion and unbalance to identify characteristics that impact motor efficiency
    • Identify power quality issues such as dips, swells, transients, harmonics and unbalance
    • PowerWave data technology captures fast RMS data, and shows half-cycle averages and waveforms to characterize electrical system dynamics (generator start-ups, UPS switching etc.)
    • Waveform capture function captures 100/120 cycles (50/60 Hz) of each event detected, in all modes, without set-up
    • Automatic transient mode captures waveform data at 200 kS/s on all phases simultaneously up to 6 kV
    • Fluke Connect¨ compatible* Ð view data locally on the instrument, via Fluke Connect mobile app and PowerLog 430-II desktop software
    • Safety rated for industrial applications 600 V CAT IV/1000 V CAT III rated for use at the service entrance and downstream
