7.3.2 Scan Rate
The next function in the main menu is the scan rate. The scan rate can be set
from .1 to 99.9°C/min. The maximum scan rate however is actually limited by
the natural heating or cooling rate of the instrument. This is often less than
100°C/min, especially when cooling.
The scan rate function appears in the main menu after the scan control function.
The scan rate units are in degrees per minute, degrees C or F depending on the
selected units.
