6.14.  Temperature Control Status 

 

 

 

When temperature control is off, the circle will be a steady gray and the label will read "off". 

When temperature control is on but the sample holder temperature is not stable, the small circle will alternate 
slowly between  green and gray and the label to it's right will read "seeking". 

When temperature control is on and the sample holder temperature is stable, the circle will be a steady green 
and the label  will read "holding". 

If an error condition occurs that causes temperature control to be turned off the circle and the caption to its 
right will alternate  rapidly between red and gray. 

 

6.15.  Heat Exchanger Temperature 

 

 

The temperature of the heat exchanger in the sample holder is displayed here. 

The heat exchanger temperature is dependent on  the temperature and the rate of flow of the water being 
circulated through  the sample holder and on the temperature control settings. 

As a warning, when the heat exchanger temperature is within 10 °C of the preset limit (typically 60 °C, the 
color of the  label will change to orange.  To correct the problem, you must reduce the temperature of the 
water (for example, by adding  ice or cold water to the coolant container). 

If the heat exchanger temperature exceeds that preset limit, temperature control will automatically be turned 
off to prevent  damage to the system. 

If temperature control does turn off, the label will turn red and an error message will display below the menu 
bar as illustrated  below; also, the 

Temperature Control Status 

will show the error number and begin flashing 

red.  The error message (and the  flashing of the status control) can be removed at any time by clicking on 
the Clear button to the left of the message. 

Once the problem with the heat exchanger temperature is corrected, you can restart temperature control by 
clicking on the 

Temperature Control On/Off checkbox 

or using the menu item 

Tools>(Temperature 

Control)>On

.
