pppp = power scale (0-unit,
1
3-kilo, 6-mega, 8-auto)
nn = number of energy
digits (5-8 --> 0-3)
eee = energy scale (0-unit,
3-kilo, 6-mega)
ddd = energy digits after
decimal point (0-6)
See note 10.
eeeeeeee = op mode screen

scale bargraph current

nn = number of phases for
voltage & current screens
(3=ABC, 2=AB, 1=A, 0=ABC)
s = scroll (1=on, 0=off)
r = password for reset in use
(1=on, 0=off)
p = password for
configuration in use (1=on,
0=off)
w = pwr dir (0-view as load,
1-view as generator)
f = flip power factor sign
(1=yes, 0=no)
If non-zero and user

settings bit g is set, this
value replaces CT
numerator in the full scale
current calculation.
