NOTE:
The phasor is drawn only when the reading is more than 200 counts. And if the
reading of V is zero, then phasor of current will not be drawn.

dA%: Historical maximum % value of
(Max (I1, I2, I3) – Min (I1, I2, I3) ) / Min(I1, I2, I3) * 100%
IUR: Current Unbalance Ratio
d02: The first number is Zero Sequence Unbalance Ratio in % (d0) of current, The
second number is the Negative Sequence Unbalance Ratio in % (d2) of
current. When IUR is displayed before d02, d02 represents the Zero (d0) and
Negative (d2) Sequence Unbalance Ratios for current.
REF: nominal voltage for transient detection reference
Sd%: threshold in % for transient detection with respect to nominal voltage (REF).
NOTE:
If the voltage of L1, L2, and L3 is not connected in right sequence, the analyzer will
show L1-3-2 in the right top corner, and beep to warn the users of incorrect phase
sequence.
