Note, that if performing an envi-
ronmental calibration at a frac-
tion of total sensor range, the
bar graphs in the main Global
Logger window will interpret
full scale range at maximum
calibration readings instead of
actual total sensor range. All
other logger operations will per-
form correctly. To revise cali-
bration settings so that the
graphs will function correctly,
follow the worksheet Calibrat-
ing the Bar Graph to Higher
or Lower Range in Appendix
B*.
