9.3 Scan
The scan rate can be set and enabled so that when the set-point is changed the
bath heats or cools at a specified rate (degrees per minute) until it reaches the
new set-point. With the scan disabled the bath heats or cools at the maximum
possible rate.
9.3.1 Scan Control
The scan is controlled with the scan on/off function that appears in the main
menu after the set-point function.
Sc=OFF Scan function off
Press “UP” or “DOWN” to toggle the scan on or off.
Sc=On Scan function on

9.3.2 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 C per minute.
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.

9.4 Temperature Display Hold
The 7102 has a display hold function which allows action of an external switch to
freeze the displayed temperature and stop the set-point from scanning. This is
useful for testing thermal switches and cut-outs. The instrument must be
powered off before attaching thermal switches or cut-outs. This section explains
the functions available for operating the temperature hold feature. An example
follows showing how to set up and use the hold feature to test a switch.
