Scan

The scan rate can be set and enabled so that when the set-point is changed the
dry-well heats or cools at a specified rate (degrees per minute) until it reaches
the new set-point. With the scan disabled the dry-well heats or cools at the
maximum possible rate.

The scan is controlled with the scan on/off function that appears in the main

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.
