Just purchased this device in the hopes of using it to monitor my sump pump. It would be great if I could just see the times that power to the sump is on/off. I'm not worried at all about consumption. The above could be accomplished if one could adjust the range in the chart. I'm sure it would be useful in providing me with the info I need, currently the range is to high to show any information at all. Any help with this matter would be appreciated.
