Dear WeatherCat fans,

I replaced the battery on my second temperature transmitter this morning and the Davis consoles insist there's a problem until midnight - even if the battery is now brand new.  I was checking on my data logger sample interval to help breno and saw that transmitter 2 battery level was shown as bad.  I had never tried before, so I pressed the Test Power System button to see if WeatherCat detected the new battery.  The red level on transmitter 2 immedately turned green - success!!  (or so I thought.)  Then the following very strange log entries appeared in the WeatherCat window:

Upon reflection, I think this a confusion between WeatherCat and the stubborn Davis console that detected an anomaly.  I know there is some way to reset the console to avoid this problem, but I'm lazy and usually just wait until midnight when the problem goes away.  However, I've learned something.  During this fickle period until the console drops the battery alert - leave the Test Power System button alone!!
