Fluke 43B/003-NLA

Single Phase Power Quality Analyzer

    • NiMH Battery provides extended operating time of 6.5 hours
    • Combines the most useful capabilities of a power quality analyzer, multimeter and scope
    • Calculates 3-phase power on balanced loads, from a single-phase measurement
    • Trends voltage, current, frequency, power harmonics and captures voltage sags, transients and inrush current
    • Monitoring functions help track intermittent problems and power system performance
    • Records two selectable parameters for up to 16 days
    • 20 measurement memories to save/recall screens and data with cursor readings
    • FlukeView® software can log harmonics and all other readings over time and provides a complete harmonics profile up to the 51st harmonic
    • Measures resistance, diode voltage drop, continuity, and capacitance
    • Users/applications manual and power quality video to help answer tough questions
    • Complete package with voltage probes and 400 A current clamp, FlukeView Software and optically isolated interface cable
    • 3 year warranty on the Fluke 43B, 1 year on accessories



    • Voltage, current, and power harmonics
    • Up to 51st harmonic
    • Total harmonic distortion (THD)
    • Phase angle of individual harmonics


    • Watts, power factor, displacement power factor (cos Θ), VA and VAR
    • Voltage and current waveforms

    Three phase

    • On-screen graphics show you how to set up 3-phase power measurements

    Sags and swells

    • Measurements are always automatically recorded to instantly show changes over time
    • Use cursors to read time and date of sags and swells


    • Catch voltage transients and waveform distortion down to 40 nS
    • Catch and save up to 40 transients
    • Correlate the cause of transient with time and date stamps


    • Voltage and current waveforms
    • True RMS voltage and current
    • Frequency
