If the Neutral circuit is chosen for the current circuit in the
arrangement shown in figure 12 this may have implications for
the calibration accuracy. The AD7751 will power up with the
V1A input active as normal. However since now there is no
current in the Phase circuit the signal on V1A is zero. This will
cause a FAULT to be flagged and the active input to be
swapped to V1B (Neutral). The meter may be calibrated in this
mode but the Phase and Neutral CTs may differ slightly. Since
under no fault conditions all billing is carried out using the
Phase CT, the meter should be calibrated using the Phase
circuit. Of course both Phase and Neutral circuits may be
calibrated.
