Split Phase
Introduction
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.
