ThermoWorks 9103 HART SCIENTIFIC FIELD DRY-WELL TEMPERATURE CALIBRATORS - Manual (Page 26)

7.3 Scan
The scan rate can be set and enabled so that when the set-point is changed the
calibrator heats or cools at a specified rate (degrees per minute) until it reaches
the new set-point. With the scan disabled the calibrator heats or cools at the
maximum possible rate.
7.3.1 Scan Control
The scan is controlled with the scan on/off function that appears in the main
menu after the set-point function.

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/minute. The maximum scan rate however is actually limited
by the natural heating or cooling rate of the instrument. This rate is often less
than 100°C/minute, 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.
Sr=10.0 Scan rate in °C/min.
Press “UP” or “DOWN” to change the scan rate.
Sr= 2.0 New scan rate
Press “SET” to accept the new scan rate and continue.

7.4 Temperature Display Hold
The calibrator has a display hold function which allows action of an external
switch to freeze the displayed temperature and stop the set-point from scan-
ning. This function is useful for testing thermal switches and cutouts. This sec-
