Ah, your readings look familiar. Don't have a Dickson Data Logger, they won't work on a Mac, but I know what happens around here. I wish I could show my bosses this. Pianos won't stay in tune here from Monday to Wednesday and there are 125 of them. Even pianos with full systems, but no undercovers or string covers. Full systems helped, but somebody's got to water the dang things. Jeff Jeff Tanner, RPT University of South Carolina
