value is below the low alarm limit.
h. R Hi - Resistance is above the high limit.
i. Off - The probe has been turned off be-
cause the IFT cannot control the heater
temperature.

3-5 QUICK REFERENCE CHART
The quick reference chart on pages 3-4 and 3-5
is designed to help you determine how to get
where you want to be in the menu system. The

determine which choices to make. Moving down
a level on the chart is accomplished by use of
the ENTER key. To move up a level on the
chart, press the ESCAPE key.
