PCE-360 Single-Phase / 1-Phase Power Meter Power-analyzing clamp meter with data logger functionality / Includes clamps, clips, leads, PC software, and data cable. For measurement in real time and over an extended time period up to 578 days @ 5 second sample rate. Stores up to 99 measurements directly in manual mode or up to 10,000,000 sets of measurements to the 4 GB internal memory in data logger mode. For analysis of voltage (V), current (A), active power (kW), apparent power (kVA), reactive power (kVar), power factor (cos Φ), phase angle (Φ), frequency (Hz), rotary field (UL > 50V), active energy (MWh), apparent energy (MVAh), reactive energy (MVArh), harmonics (1 … 63 order, via software) and waveforms (via software). Battery-saving automatic shutdown after approximately 30 minutes of inactivity.
