I had the same horrible problem. Couldn't ever get the thing to work
right. I am really reluctant to try again. They sold us a "fix" which was
no better than the original and then lost interest. Would they do the same
thing again?  I have friends who just use their flourometer, seems to do
just fine!  I intend to stay far away from them and suggest you do the
same. Perhaps that will make them more helpful in the future!
