Lake Shore Model 332 Temperature Controller User’s Manual
4.4 INPUT SETUP
The Model 332 supports a variety of temperature sensors sold by Lake Shore and other manufacturers.
An appropriate sensor type must be selected for each of the two inputs. If the exact sensor model is not
shown, use the sensor input performance chart in Table 4-1 to choose an input type with similar range
and excitation. For additional details on sensors, refer to the Lake Shore Temperature Measurement
and Control Catalog or visit our website at www.lakeshore.com.

4.4.1 Diode Sensor Input Setup
Diode type supports Silicon and Gallium-Aluminum-Arsenide (GaAlAs) diodes detailed in Table 4-1.
More detailed specifications are provided in Table 1-2. Input ranges are fixed to 0
– 2.5 V for silicon
diodes and 0 – 7.5 V for GaAlAs diodes. Both use a sensor excitation current of 10 µA.
To setup a diode sensor input, press the
