Watts Up? didn't design the meters we looked at today with NAS power testing in mind. The truth is they may not have even had the computer industry in mind at all. The meters are accurate; we can see a staggered spin up in a server. They are also easy to use. When I go exploring for new test equipment, and applications, I look for the easiest way to unveil the data I need to finish a review. Sometimes my quests take months, like the 120-multiclient test, but other times I strike gold the in first round.
Finding the Watts Up? meters were just that: a gold rush. The meters measure the data I need to present in my NAS reviews. They also make getting the data easy, and finally, they do it without giving me crispy fingers.
Today, we only tested the meters with a NAS, but over the last few weeks, I've measures everything from home theater subwoofers to LED night lights. Our meters are rated at 15 amps due to the plug types; the hardware is capable of a 20 amp load though. That gives you enough headroom to measure appliances like refrigerators, clothes washers, and for that matter, just about anything that plugs into a 120v wall socket.
The star of the show today is the flagship .Net model with relay switching, and Ethernet capabilities. The free online membership to retrieve your collected data is limited to just one sample every fifteen minutes. It's a value that doesn't work for us, but everyone's application is different. The large membership package gives you near real-time access to data in one-second intervals, one year of archive time, and up to 25 rules. The only issue is that the Professional level membership is a $50 a month investment.
