14. PROBLEM:
Message on the screen displays no moisture content reading.
SOLUTION:
1. When a moisture content reading is not shown, the water ac-

(a) The isotherm equation calculates a moisture content that
is less than 0% or greater than 100% with the given water
activity.
(b) The control temperature is significantly different than the
isotherm temperature. Make sure that the sample wa-
ter activity and the instrument controlling temperature
