- What's Included
The Watts Up? PRO ES measures voltage and current information thousands of times a second, yet is simple to use. Only six values are displayed in the main modes. Additional information is available in the detail mode. Clear English wording on the LCD is used to describe what is displayed.
Super Fast Response Allows for Additional Data Collection
The Watts Up? PRO ES has an incredibly fast response time, enabling you to "see the surge" of power when appliances are first turned on. Input is via a 6' electric cord, output is via an outlet on top of meter. The peak value display captures this surge so it's displayed even if it happens too fast to see live. The minimum voltage display shows the line quality and voltage dips. Minimum current and minimum watts can be used to monitor variances in appliances that run continuously. Watts Up? PRO ES also measures true RMS power (including power factor) which is what utilities charge for. Watts Up? PRO ES offers all the features of the PRO model, but includes additional memory to hold over 120,000 records. And compared to the standard Watts Up?, this PRO ES and the Watts Up? PRO include additional analysis tools like the Payback Calculator, which automatically calculates the time required for a new energy-efficient appliance to pay for itself. Monthly savings are highlighted, so you may easily compare to the purchase price of the new appliance.
The Watts Up? PRO ES stores 6,500 data points in non-volatile memory, which can be retrieved even if power is lost. The sample rate resolution increases over time, beginning at one second (sample rate equals total time divided by 1000), so years of usage can be accurately recorded. The included serial cable and software program allow the data to be quickly downloaded to a PC where the software creates a data table and easily manipulated graphs. The data can also be exported in a comma-delimited format to popular spreadsheet programs for further analysis.
Accuracy is of the displayed value, not the range. Some devices claim a smaller number for accuracy but it refers to the range. For instance, a specification of 0.2% of the range sounds good, but it is actually 3.6% of the display (.02 * 1800 = 3.6), which is a worse accuracy.
For indoor use only.
