• Current, Average, Minimum, and Maximum values  
• A, B, C, and D frequency weighting filters  
• Linear (unweighted) mode  
• Fast or Slow response modes  
• High, Normal, or Low time resolution settings  
• Start or stop measurements anytime with a single tap  
• Calibration adjustment up to ±10 dB for improved accuracy  
• Multiple display styles with digital and analog views
