Relation between HI and OK
When the measured value falls below the upper limit value, OK is output
immediately.
Even if the measured value exceeds the upper limit value, HI is not output
immediately. HI will be output when the measured value exceeds the hysteresis
width, or when the hysteresis time has elapsed.
Relation between LO and OK
When the measured value falls below the lower limit value, LO is output immediately.
Even if the measured value exceeds the lower limit value, OK is not output
immediately. OK will be output when the measured value exceeds the hysteresis
width, or when the hysteresis time has elapsed.
