  • The Fluke 41B Harmonics Analyzer combines the ease of use of a digital multimeter, the visual feedback of an oscilloscope and the power of a harmonics analyzer in a single instrument. If you're testing power on three-phase systems or trouble-shooting harmonics on non-linear loads, no test tool makes it easier.

    The Model 41B is ideal for further analyzing data and optimizing system performance. Use the Fluke 41B's FlukeView® software (included) to download acquired data to a printer or an MS-DOS® or Windows® compatible computer for analysis and presentation.

    • Waveform
    • Bargraph showing harmonic levels
    • Numeric values

    Real-time Display Updates

    Display updates three times a second for a dynamic view of actual circuit conditions.

    Comprehensive Measurements

    Measure rms, peak and total harmonic distortion (THD) for complex voltages and currents - with no manual calculations required. Three Phase Readings

    Three-Phase readings

    From a simple single-phase measurement, automatically calculates three-phase power for 3-wire balanced loads (typically 5% or less imbalance). To make the single-phase measurement, simply connect the meter as shown and select the 3º, 3C watts display.

    System Critical Data

    Immediate readings of Power Factors, KVAR, Crest Factor, K-Factor.

    Display Harmonics individually to the 31st

    Min/Max and Average Recording

    Data Storage

    Up to eight complete measurement sets.

    Isolated Serial Interface

    Communications with a serial printer or DOS® or Windows®-compatible computer.

    Safety Designed

    To meet the latest standards: IEC 1010-1, pollution degree 2, Installation Category III, material group II, 600 V. Double insulated protection as described in IEC 1010-1, Annex H.

    Display

    One cycle of the fundamental waveform and its frequency. Instantaneous voltage at cursor position.

    Application

    Application

    Identifying sources of harmonic currents. Obtaining data for designing, specifying or sizing transformers, filters, etc.

    Display

    %-fundamental or %-rms, rms value, frequency, and phase angle of fundamental or harmonic currents (up to 31st), as selected by cursor from bar graph. Application

    Application

    Identifying sources of harmonic currents. Obtaining data for designing, specifying or sizing transformers, filters, etc.

    Display
