Function or LSB Value
Nominal RMS current applied to
all elements during auto-calibra-
tion (LSB = 0.1V). Power factor
must be 1.
This feature is approximated using
the CE’s sag detection.)
t = (2*PulseWidth + 1)*397µs,
0xFF disables this feature. Takes
effect only at start-up.
Units of TEMP_RAW, from CE.
The value read from the CE must
be entered at this address.

Units from CE.
ADC counts, logically shifted right
by 9 bits. Note: battery voltage is
measured once per day, except
when it is being displayed or
requested with the BT command.
