4.3.2 Display Contrast
The front panel LCD display contrast can be adjusted for optimal viewing. The default
value should work well in most standard room temperature environments, but devia-
tions from room temperature, and extreme viewing angles can cause the display con-
trast to require adjustment for optimal viewing.

4.4 Input Setup
The Model 336 supports a variety of temperature sensors manufactured by
Lake Shore and other manufacturers. An appropriate sensor type must be selected for
each input. If the exact sensor model is not shown, use the sensor input performance
chart in TABLE 4-7 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.
Any unused input should be set to disabled.
