2.18.1 SENSOR SELECT Switch
The SENSOR SELECT snitch is used to select sensor type and, in the case of thermistor sensor, the source current
level. Table
2.1 shows the SENSOR SELECT positions and corresponding position code. When the sensor switch
is changed during
TEC mode operation, the new sensor position code will be indicated on the TEC display for
three seconds.

able 2.4 SENSOR SELECT Switch Positions
The 10 uA and 100 uA designations are for the current source level; thermistor sensor type is implied. When using
a thermistor, the supply current depends on the thermistor operating temperature range and the required
temperature resolution. Guidelines for setting this switch are contained in Appendix
B.
The AD590 sensor operates as a current source which is proportional to the sensed temperature. The LM335
sensor operates as a voltage source which is proportional to the sensed temperature. Both of these sensors are
approximately linear over their operating ranges. When they are used, the constants
C1 and C2 are used for a two-
point conversion. For more information on setting the constants for use with these sensors, see Section
2.9.5 and
Appendix
C.
2.18.2 TEC Connector
At thc r~ght of center, when facing the back panel, you will find the 15-pin D-connector for the TEC MODULE.
Th~s connector is used for the input and output connections, as shown by the pin-out diagram of Figure 2.12.
