6.3.2 Scan Rate
The scan rate can be set from 0.1 to 50.0°C/min. The maximum scan rate, how-
ever, is actually limited by the natural heating or cooling rate of the instrument.
This rate is often less than 50°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 Celsius per minute, regardless of the selected
