Electronic Educational Devices - WATTS UP PRO Power Analyzer/Watt Meter (USB Interface) Watts Up PRO Digital Electric Meter with USB Interface Made in USA Standard 16 Watts Up? Displays PLUS Computer Software/PC Interface Automatic Data Graphing Payback Calculator for New Appliances and Much More. This Batch Data Download Lets You Audit a Day or More of Energy Usage. Now Optional Real Time Software Upgrade Available: Constant Real-Time Download Notifies You of Line Voltage Dips or Demand Load Increases. Watts Up? PRO data logger function records all data into non-volatile memory. Data is not lost if power goes out . One thousand twenty-three data points are stored. Initial sampling rate resolution is one second. Sample rate resolution increases over time (sample rate equals total time divided by 1023). Accurately record years of electrical usage. Spreadsheet calculator used to determine logging intervals based on how long you are logging. For instance, the calculator. gives an interval between data will be 1 hour, 8 minutes and 16 seconds if you have logged data for 6 weeks. Create a data table with easily manipulated graphs. Connect RS232 port to a PC. Export data and graphs to popular spreadsheet and word processor programs for further analysis. The PRO also records any power interruptions helpful when auditing several devices. In addition, the Pro is capable of real time logging. The communication protocol is fully documented in the help file, including a list of commands required for real-time logging using other software. Sixteen Values displayed: Cost, in dollars and cents Average monthly cost Power factor True power Average monthly kwh Minimum RMS voltage Maximum RMS voltage Cumulative power (kwh) Power cycle (PRO models only, on computer interface) Minimum RMS current Maximum RMS current Time Minimum wattage Maximum wattage RMS Voltage Duty cycle RMS Current Watts Up? PRO Specifications: Internal Memory for 1,023 Records. State-Of-The-Art Microprocessor Digital Design 120 VAC, 60 Hz, 15 amps continuous: Below 60 watts, amps and power factor lose accuracy. RMS stands for Root Mean Square, and it is the most basic term for representing power output. True RMS power measured and displayed +/- 3%, +/- 2 counts of the displayed value for loads above 10 watts +/- 5%, +/- 3 counts of the displayed value for loads below 10 watts Accuracy is of displayed valuse, 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. RS232 Interface. (USB to RS232 Adapter NOT Included). included Cable (connects to the PC USB port) Software download included of most recent software version. See manual. Power Cycle.
