voltage, as 3-5-5: the upper left corner of the screen displays "U_max", represents
the maximum voltage, 'a', 'b', 'c', respectively, A-phase, B-phase, C-phase voltage,
unit is V or kV. Occurrence time of the maximum value is displayed at the bottom
of the screen.
Note: The only show in the 3-phase 4-wire page.
Screen 2：Minimum value of phase voltage
The screen displays the minimum value of the
3-phase voltage, as shown in fig. 3-5-6: the upper left
corner of the screen displays "U_min", represents the
minimum voltage, 'a', 'b', 'c', respectively, A-phase,
B-phase, C-phase voltage,unit is V or kV. Occurrence
time of the minimum value is displayed at the bottom
of the screen.
Note: The only show in the 3-phase 4-wire page.
Screen 3：Maximum value of line to line voltage
The screen displays the maximum value of line to line voltage, the upper left
corner of the screen displays "U_max", represents the maximum value of line to line
voltage, 'ab', 'bc', 'ca' denote the line voltage AB, BC, CA, with the first screen display
similar .
Screen 4：Minimum value of line to line voltage
The screen displays the minimum value of line to line voltage, upper left corner
of the screen displays "U_min", represents the minimum value of line to line voltage,
'ab', 'bc', 'ca' denote the line voltage AB, BC, CA, with a second similar screen
display .
Screen 5：Maximum value of current
