Features

• Power inverter efficiency: Simultaneously measure AC output power and DC input power for power electronics systems using optional DC clamp.

• PowerWave data capture: Capture fast RMS data, show half-cycle and waveforms to characterize electrical system dynamics (generator start-ups, UPS switching etc.).

• Energy loss calculator: Classic active and reactive power measurements, unbalance and harmonic power, are quantified to pinpoint the fiscal costs of energy losses.

• Troubleshoot real-time: Analyze the trends using the cursors and zoom tools.

• Highest safety rating in the industry: 600 V CAT IV/1000 V CAT III rated for use at the service entrance.

• Measure all three phases and neutral: With included four flexible current probes with enhanced thin flex design to fit into the tightest places.

• Automatic Trending: Every measurement is always automatically recorded, without any set-up.

• System-Monitor: Ten power quality parameters on one screen according to EN50160 power quality standard.

• Logger function: Configure for any test condition with memory for up to 600 parameters at user defined intervals.

• View graphs and generate reports: With included analysis software.

• Battery life: Seven hours operating time per charge on Li-ion battery pack.
