Figure 7-2 Voltage Parameter Diagram 
Voltage parameters of UTD2000 series DSO include: 
Max value (Max): The voltage value from waveform highest level to GND. 
Min value (Min): The voltage value from waveform lowest level to GND. 
Top value (High): The voltage value from waveform flat top to GND. 
Bottom value (Low): The voltage value from waveform bottom to GND. 
Middle value (Middle): Half of the sum value of High and Low voltage value. 
Peak-peak value (Pk-Pk): The voltage value from waveform highest level to waveform 
lowest level. 
Amplitude (Amp): The voltage value from waveform top to waveform bottom. 
Mean value (Mean): The average amplitude value of waveform. 
Cycle mean (CycMean): The average amplitude value of waveform of one cycle. 
Root Mean Square (RMS): The effective value. The converted energy based on AC signal. 
The DC voltage corresponding to the generating equivalent energy, converted energy.   
Cycle RMS (CycRMS): The converted energy in one cycle based on AC signal. The DC 
voltage corresponding to the generating equivalent energy.
