Split Phase - Dranetz HDPQ-DN-MVB Quick Reference Manual

Split Phase

When making split phase measurements, use both channels A and B for
voltage and current connections. The Neutral is chosen as the reference
for measurement purposes. The figure also shows voltage connection
using channel D as a differential input for measuring neutral to ground
voltage. Neutral to ground measurements are important but optional.
NOTE Be sure to connect the current probe with the arrow
pointing towards the load or an erroneous power reading
will result.
