• Adds PC interface, graphing software and internal memory!

Watts Up PRO includes all the displays of the standard Watts up? meter but also comes with software and USB PC interface. The software automatically graphs all data and includes an integrated analysis tool, called the Payback Calculator, which automatically calculates the time required for a new energy efficient appliance to pay for itself. Monthly savings are calculated and then are compared to the purchase price of the new appliance. As a data logger, the PRO records all data into non-volatile (stored even if power is lost) memory. Over one thousand data points can be stored, starting with a sampling rate resolution of one second. The sample rate is user selectable or can be automatically set (resolution decreases over time) so years of usage can be accurately recorded. The included cable allows for USB port connection of a PC and when used with the included software, data can be quickly downloaded to a computer where the software creates a data table and easy to manipulate graphs. The data and graphs can than be exported to popular spreadsheet and word processor programs for further analysis. Note how the graph at the right identifies the defrost cycle on a refrigerator. Watts Up PRO also records any power interruptions, which is extremely handy when performing an audit of several devices. In addition, the Pro is capable of real time logging when used with the additional Real Time Software (not included). 120v 60hz.
