ADJ : Threshold Value Fine Adjustment Mode
This mode allows fine adjustment of the ‘threshold value’ setting.
When the incident light intensity display has been selected, the threshold value
can be adjusted in increments as low as a one digit.
When the percentage display has been selected, the threshold value can be
adjusted in increments of one digit (varies depending on the ‘threshold value’).
However, when FX-305(P) is in window comparator mode, the percentage display
function cannot be utilized.
* The factory setting is; FX-301(P): 40, FX-301(P)-HS: 80,
FX-305(P) output 1: 80, FX-305(P) output 2: 120.

When set to ‘L-ON’, the output will be ON if the incident light intensity becomes
greater than the ‘threshold value’.
When set to ‘D-ON’, the output will be ON if the incident light intensity becomes
less than the ‘threshold value’.
When set to ‘L-ON’, if the incident light intensity is between the two ‘threshold
value’ levels, the output will be ON. If the incident light intensity is outside of the
two threshold value levels, the output will be OFF.
When set to ‘D-ON’, if the incident light intensity is between the two ‘threshold
value’ levels, the output will be OFF. If the incident light intensity is outside of the
two threshold value levels, the output will be ON.
This mode allows the selection of output operation from either L-ON (Light-ON), or
D-ON (Dark-ON).

* The output time ‘T’ can be set by changing
the timer period in timer setting mode
(initial value: 10 ms).
* The output time ‘T’ can be set by changing
the timer period in timer setting mode
(initial value: 10 ms).
For L-ON, output is ON for a constant period of time when the incident light
intensity is rising.
For D-ON, output is OFF for a constant period of time when the incident light
intensity is rising.
For L-ON, output is ON for a constant period of time when the incident light
intensity is trailing.
For D-ON, output is OFF for a constant period of time when the incident light
intensity trailing.
