Figure 6-23 is our test of the incubator using open-loop control. Note that we allowed
temperature to stabilize somewhat prior to changing the drive. With your experience of
the system curve you can begin to approximate whether drive is too much or too little
after a short while.

Close the Debug Terminal.
Open StampPlot macro sic_pc_incubator_open_loop.spm.
Connect and plot.
Adjust the PWM drive slider to achieve a stable temperature in the desired band
of 101.5 °F +/− 1 °F (yellow band in plot).
Once stable for 2 minutes, lightly blow continuously on the incubator test tube.
The fan may also be used if moved the farthest possible distance away. The fan
will also draw down the power supply voltage, causing heat output of the resistor
to drop in addition to increased losses.
