About This

• Comprehensive Test Function: Real-time display of voltage/current waveforms (4 channels each). Measures true RMS, DC components, peak, min/max values, harmonics up to 50x, THD, power values, and displays phasor diagrams and harmonic histograms
• Capture and Monitoring: Detects instantaneous voltage/current changes, including fluctuations, swell, sag, interruptions, and transient events. Stores up to 150 transient waveforms for detailed analysis
• Start-up Current Monitoring: Monitors inrush and start-up currents, displaying rise/fall curves, envelope curves, and waveforms. Records up to 100s of data, capturing instantaneous values and waveforms for accurate analysis
• Extensive Recording and Storage: Records 123 parameters, including harmonics up to 50x and generates trend diagrams. Supports long-term data recording with the ability to record 20 parameters every 5 seconds for up to 300 days
• Customizable Alarm Function: Set parameter limits to monitor over-voltage, over-current, unbalance, harmonic distortion, frequency, active power, and more. Generates alarm logs when limits are exceeded for proactive monitoring
• Screen Capture Function: Capture and store up to 60 screenshots of test pages, including voltage waves, harmonic histograms, and phasor diagrams, with automatic recording of time and test mode
• USB with PC allows real-time display of power quality analysis, reading of transient waveforms, trend charts, alarms, and screenshots for comprehensive data review
• User-Defined Settings: Customize time/date, display contrast/brightness, phase line colors, connection mode, power network type, current clamp, voltage test ratios, and menu language (Chinese/English) for tailored operation
• Help Menu: At each stage of operation, press help key at any time to obtain relevant help information.
