Three-Phase Power Quality Analyzer (BJMDZ-3540) is a high-accuracy test instrument with harmonic content of voltage fluctuation and flicker and phase imbalance of power quality problems.
 Feature:
• Power inverter efficiency: Simultaneously measure AC output power and DC input power for power electronics systems using optional DC clamp.
• PowerWave data capture;
• Waveform capture:BJMDZ-3540 capture  cycles (45-55Hz) of each event that is detected in all modes, without set-up.
• Troubleshoot: Analyze the trends using the cursors and zoom tools.
• Highest safety rating in the industry
• Measure all three phases and neutral: With included four flexible current probes with enhanced thin flex designed to fit into the tightest places.
• Automatic Trending: Every measurement is always automatically recorded, without any set-up.
• 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: Up to 8 hours operating time per charge on Li-ion battery pack.
