Hardware Functions
The following values are output according to the setting for non-measure-
ment.

Maximum output voltage: Approximately 5.5 V
Maximum output current: Approximately 23 mA
The averaging operation is cleared for the reset input. The judge-
ment output response thus may be slower than normal immediately

Judgement Outputs
There are three judgement outputs: HIGH, PASS, and LOW.
The following table and illustration show the timing of each output.
Threshold Values
The threshold values form the boundaries between the HIGH, PASS,
and LOW outputs for the measured value.
There are two threshold values: The HIGH threshold and the LOW
threshold. The threshold values contain hysteresis.
Hysteresis
The hysteresis (hysteresis width) is the difference between the operating
and releasing values. If the hysteresis is too small, chattering may occur.
If it is too large, releasing may be difficult.
Larger than or equal to HIGH threshold
Smaller than or equal to HIGH threshold − Hysteresis
Smaller than or equal to LOW threshold
Larger than or equal to LOW threshold − Hysteresis
