Selection of 3-phase or individual phases L1, L2 and L3, displays:
• The total THD
• The MIN and MAX instantaneous values
• The parameters for the harmonic order selected by the cursor:
- Percentage in relation to the fundamental
- RMS value and phase angle in relation to the fundamental component
• MIN, MAX instantaneous values for the selected current harmonic
MIN, MAX values are reset each time the cursor position is changed.
