Defining Interharmonics (A function only)
The Logger uses an interharmonics calculation to measure mains signaling, or ripple
control signals. These signals are used in some parts of Europe to control industrial
equipment and lighting. Logging of interharmonics is optional. To define interharmonics
to log:
1. Click Edit Interharmonics from the ”Set up for Logger function A” screen. The
screen that enables defining of ripple control signals and interharmonics appears.
This is where you can select the frequency of the ripple control signal, give a
descriptive name to the signal, and select the measurement method for the signal.
