Cryo-con Model 24C
Basic Setup and Operation
CalGen
Menu, 2-point Diode Sensor
#300.000 Capture
The exact temperature at a point near 300K is entered here.
Note: if CalGen
has not been used on this channel before, the
word Capture will appear. Otherwise, the last captured sensor
reading will appear.
Unit: 0.98257V
Pressing the
Enter
key will capture the existing unit reading and
associate it with the 300K point. The value will be displayed on
line 1 above.
#77.000 Capture
The exact temperature at a point near 77K is entered here.
Unit: 1.28257V
Pressing the
Enter
key will capture the existing unit reading and
associate it with the 77K point. The value will be displayed on line
3 above.
New Curve
Pressing the
Enter
key will initiate the generation of a new curve.
Table 33: CalGen Menu, 2-point Diode Sensor
The two temperature points, one near 300K and the other near 77K may be entered
in any order.
To enter the 300K-point, change the field 300.000 to the exact required temperature.
Then, allow the temperature measurement to stabilize. When the measurement is
stable, select the Capture field next to the temperature field. This will cause the Model
24C to capture the sensor reading and associate it with the specified temperature.
When a sensor reading is captured, the actual reading will be displayed in place of
the word Capture. Note that the user may capture a new reading by selecting this field
again, even if it already contains a reading.
The Unit field of this screen will display the actual sensor reading in real time. This will
allow the user to determine when the unit is stable at the required temperature.
Next, the second temperature must be entered in the same way as before.
