The Isotherm tab is the main screen and displays each time the VSA turns on. If the Isotherm
tab screen does not appear, refer to Section9.1 for troubleshooting. Operators can initiate
a new test from this screen by pressing the wizard icon (third button from right). If a test is
already running, this screen displays the latest test values including water activity, weight or
% moisture content and temperature. Pressing the second button activates the chart view.
