8. After the temperature has settled around 40 degrees, increase the “Heat Source
Power Dissipation” to 100% (note the exact temperature for 100% because your
board may be different than the resulting plot due to heat source component vari-
ation and ambient temperature) to force the temperature to exceed the
45-degree target that was set for the alert threshold on the Ext 1 channel. Notice
the ALERT LED on the board turn on. When lowering the “Heat Source Power
Dissipation” back to 80%, the LED will turn off after the temperature falls below
the set target.
The plot from the “Demo Data Acquisition” chart should look like the picture below.
