Tool Review: Watt's Up with no onboard clock?
Summary: 3 Stars
This product works reasonably well if you want to know how much energy a specific appliance or piece of equipment is using, but pretty useless for trying to monitor any kind of short term power fluctuations. You would think that when they we designing a $175 meter, they could have included a 98¢ clock chip to provide some accurate time stamping on the data samples. Instead it relies on a kind of hinky software patch to address this problem. When you are looking to match this meter's data log with another log, say from a UPS, this software time stamp kludge is just not accurate enough.
So if you just want to know how much your refrigerated is costing you to run or how much juice your TV is drawing when it's turned off this is a good choice. If you want to find out why the UPS connected to your computer switches to batter every couple minutes, forget about it.
