Changing the time between temperature sample periods
The Thermometer application can sample the temperature at a variable rate determined by the

The user sets the sample rate on the Options screen by selecting the appropriate options in the
“Sample Interval” area. Sample intervals may be chosen between one per second to one every

Simulating temperature measurements
The Temperature display program allows you to simulate temperature readings instead of

Checking the “Simulate Temperature” box will cause the thermometer to enter a test mode in
which a series of random temperature readings will be displayed.
