While channel 4 is often used to measure the neutral line of 3-phase 4-wire connections, there are a vari-
ety of other uses since it is isolated from the instrument's other channels.
This is an extremely broad range of applications that extends from monitoring DC power supply systems
to monitoring hardware internal power supplies. Since events can be detected using DC measured val-
ues, it is possible to monitor the AC power supply on channels 1 through 3 when DC power supply distur-
bances occur.

ment
