This lightweight handy type is convenient for carrying and simple to handle! (Weight: approx. 310g)

The presence or absence of harmonics can be scanned safely and accurately on high-voltage and lbw-voltage equipment in live lines.

The second to 40th harmonic current content and total distortion factor are calculated by 512-point fast-Fourier-transform, and are displayed and stored in memory. (Up to 40th harmonic current can be scanned in a few seconds.)

Fast-Fourier-transform calculation is optimized by setting to 50 or 60Hz commercial frequency with the frequency selector switch.
