  • PowerWave data capture ? capture fast RMS values to see every waveform so you can determine how the voltage, current and frequency values are interacting
  • Power inverter efficiency ? Power inverter efficiency
  • Energy monetization ? calculate the fiscal cost of energy waste due to poor power quality
  • Energy assessment ? quantify the before and after installation improvements in energy consumption to justify energy saving devices
  • Frontline troubleshooting ? quickly diagnose problems on-screen to get your operation back online
  • Predictive maintenance ? detect and prevent power quality issues before they cause downtime
  • Long-term analysis ? uncover hard-to-find or intermittent issues
  • Load studies ? verify electrical system capacity before adding loads


  • 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.
