The Cx Monitor® is a power quality monitor adapted
specifi cally for the needs of a commissioning agent.
The monitor gathers all of the voltage and current
data required for all of the commissioning tests as well as
provides a means for gathering wireless T&H or DC voltage
data for over one hundred (100) locations! The Cx Monitor®
is equipped to simultaneously monitor in real time, voltage on
ten (10) separate channels and current on fi ve (5) separate
channels. This is ideal for documenting the testing of generators, UPS’s and transfer switches.
