Lake Shore Model 331 Temperature Controller User’s Manual
4.5.1
Diode Sensor Curve Selection
Once the input is setup for the Silicon or Gallium-Aluminum-Arsenide Diode (Paragraph 4.4.1), you
may choose a temperature curve. Standard curve numbers 1 thru 4, or none, being relevant choices.
You are also given the choice of “None.” You may also choose from any appropriate User Curves
stored in Curve Numbers 21 thru 41. Data points for standard diode curves are detailed in Tables D-1
thru D-3 in Appendix D.
Press the
Input Setup
key. Press the
Enter
key until you see the curve selection screen shown
below.
Select for InputA °®
Curve 01 DT-470
Use the
s
or
t
key to cycle through the sensor curves until the desired curve is displayed. Press the
Enter
key to return to the normal display.
NOTE:
Standard diode curves and typical sensor performance (Table 1-3) are calculated
using 10 µA excitation. Sensor temperature response characteristics will be altered
if 1 mA excitation is selected.
4.5.2
Resistor Sensor Curve Selection
Once the input is setup for the Platinum, Rhodium-Iron, or various NTC RTD sensors (Paragraph
4.4.2), you may choose a temperature curve. Standard curve numbers 6 and 7 being relevant to
Platinum, or curves 8 and 9 being relevant to Rox™ sensors. You are also given the choice of
“None.” You may also choose from any appropriate User Curves stored in Curve Numbers 21 thru 41.
Data points for resistor curves are detailed in Tables D-4 thru D-6 in Appendix D.
Press the
Input Setup
key. Press the
Enter
key until you see the curve selection screen shown
below.
Select for InputA °®
Curve 08 RX-102A-AA
Use the
s
or
t
key to cycle through the sensor curves until the desired curve is displayed Press the
Enter
key to return to the normal display.
4.5.3
Thermocouple Sensor Curve Selection
The following thermocouple screens are only displayed when the Model 331 hardware is configured
at the factory with one or two thermocouple sensor inputs; being Model 331X-T1 or -T2.
Once the input is setup for the thermocouple input voltage (Paragraph 4.4.3), you may choose a
temperature curve. Press the
Input Setup
key. Standard curve numbers 12 thru 16 being relevant.
You are also given the choice of “None.” You may also choose from any appropriate User Curves
stored in Curve Numbers 21 thru 41. Data points for thermocouple curves are detailed in Tables D-7
thru D-11 in Appendix D. Press the
Enter
key until you see the curve selection screen shown below.
Select for InputA °®
Curve 16 AuFe 0.07%
Use the
s
or
t
key to cycle through the sensor curves until the desired curve is displayed. Press the
Enter
key to return to the normal display.
