Hi. Is there anyone who is a 'guru' with these wonderful meters? Just when I think I have the read-pay-read process right something else comes up. This last time I read...paid...re-read (power went back on and thought all was well. Aug 1 power goes off! Had to re-read the card into the meter. Trying to figure if there is something I missed in the process. Would love to get one of the "old" ones but guess that just does not happen.
