Fast Transient
Very fast transients have limited energy due to their short duration. They are caused by arcing faults, such as bad brushes in motors, and are rapidly damped out by even a few meters of distribution wiring.

Enabling Additional Channels
When creating a setup file a particular power wiring connection needs to be selected. This instructs the instrument on how to calculate the power and energy. When the power wiring connection is create the required input channels are automatically enabled.In some cases the operator may wish to enable additional channels for other measurements. This will not affect the power or energy measurements.
