Simply plug any 120 VAC appliance into Watts up?, and the meter instantaneously displays the wattage being used. Watts up? measures true power (including power factor) which is what utilities charge for, not just RMS voltage.
Press the mode button and the display shows the cumulative amount of kilowatt hours consumed since the meter was plugged in, or last reset. Press the mode button again and the display shows the cumulative time Watts up? has been plugged in, so controlled experiments are easily accomplished. Finally, press the mode button again and the display shows the amount of money the electricity has cost. Watts up? uses a default rate of 8 cents per kilowatt hour, or simply change the rate to match your local area.
Any 120 VAC appliance can be plugged in. A 15 amp circuit breaker protects against overloads. Watts up? can be plugged in for seconds, days, or weeks. The decimal point on the 3 digit display "floats" to display the highest resolution possible. For instance, in dollar mode, the display shows a range of $.001 to $999. Watts up? is UL listed to standard 3111-1.
This product is also available for rent, $20/week + shipping. |
