• Display of Waveform with Peak Values (1024 samples/period)

• Analysis of Total Harmonic Distortion (THD-F)

• Maximum Demand (MDkW, MW, kVA, MVA) with programmable period

• Adjustable CT ratio (1 to 3000) and VT ratio (1 to 600)

• Graphic Phase diagram with 3-Phase system parameters

• 3-phase Voltage or Current Unbalanced Ratio (VUR, VIR) and Unbalanced Factor (d0%, d2%)

• Calculated Unbalanced Current through Neutral Line (In)

• Capture 28 Transient events (including Dip, Swell and Outage) with programmable threshold (%)

• Optically isolated USB interface with software to download
