Watts Up? Meters
The three models we're looking at today, all look the same from the top other than the product label. We ordered our meters with a standard 3-hole UO plug, but you can order meters with an IEC 320 C14 plug as well.
The front display is capable of showing eighteen different metrics: Current Watts, Minimum Watts, Maximum Watts, Power Factor, Volt Amp (apparent PWR), Cumulative Watt Hours, Average Monthly Kwh, Elapsed Time, Duty Cycle, Frequency (Hz), Cumulative Cost, Average Monthly $, Line Voltage, Minimum Volts, Maximum Volts, Current Amps, Minimum Amps, and Maximum Amps.
The .Net model has two ports: Ethernet, and USB. The Pro and Pro ES only have USB, and the baseline Watts Up? is void of both ports.
The meters plug into the wall to get power, and the plug at the top is your metered outlet.
You may assume the front panel has limited functionality with just two buttons, but we managed to perform nearly every setting change with these buttons.
Rubber feet keep your meter from sliding around on a desk or table.
As we mentioned, the other models look nearly identical to the .Net model we've already shown.
Also as mentioned, the Pro and Pro ES only have the USB port.
