s SELF-DIAGNOSTIC FUNCTION
With this function, the E3X checks changes in environment
conditions (especially a change in the ambient temperature) and
self-diagnoses the resistance against the changes. The result is
shown by the indicators or an output signal.

Displays
q Stable Operation Indicator: Changes in environmental
conditions (changes in the ambient temperature, the
operating voltage, or the volume of dust) are checked and
the resistance against them are self-diagnosed. The result
is shown via the indicator.
q Light Reception Indicator: The amount of light received is
shown by this indicator.
Output:
q The resistance against changes in environmental
conditions is shown by the indicator and the result is
output.
