Temperature Probe Module, and the bottom display ‘
Figure 4: Module Panel pertains to the last Temperature Probe Module. When
the test switch is depressed, the display must indicate
25 :t: .4°C; the display will be blank if no module is con—
nected. Releasing the test switch will return the display
to its prior state.
At the top of this module are the controls and displays

99.9 Indicates that the temperature is over
50°C.
Blank Indicates that there is no temperature
conversion module or that the module is
not functioning correctly.
The top display also displays the selection range and
