Lake Shore Model 332 Temperature Controller User’s Manual
4.5 CURVE SELECTION
The Model 332 supports a variety of temperature sensors sold by Lake Shore and other manufacturers.
After the appropriate sensor type is selected for each of the two inputs (Paragraph 4.4), an appropriate
curve may be selected for each input. The 332 can use curves from several sources. Standard curves
are included with every instrument and numbered 1
– 20. User curves, numbered 21 – 41, are loaded
when a sensor does not match a standard curve. CalCurve options are stored as user curves. SoftCal
calibrations are stored as user curves or user can enter their own curves from the front panel
(Paragraph 5.2) or computer interface (Chapter 6). The complete list of sensor curves built in to the
Model 332 is provided in Table 4-2.
During normal operation, only the curves related to the input type you have selected are displayed. If
the curve you wish to select does not appear in the selection sequence make sure the curve format
matches the recommended format for the input type selected. Refer to Table 4-1.
NOTE: The sensor reading of the instrument can always be displayed in sensor units. If a temperature
response curve is selected for an input, its readings may also be displayed in temperature.
