Attached is a screenshot from HOBOware that depicts a data file generated from a HOBO UX90-001 Runtime logger connected to a CSV-A8 current switch that was clamped onto one of the 240VAC lines feeding an electric hot water heater. The logger was configured for Runtime logging at a one-hour logging interval. What you see is the total runtime in minutes and seconds in each hourly logging interval, as well as the percentage of time the heater was on per interval. Other available series that are available for plotting are time and percentage off per interval.
Note that if a UX90-004 Motor On/Off logger was used with the CSV-A8 connected to its external input, the data would be presented the same way.
