6.COMPARISON FUNCTIONS

6-2. Hysteresis

The hysteresis value may be determined so as to allow a margin for timing the turning off

of the HI-LO limit comparison. Normally, it is turned on when the indicated value

exceeds the HI limit and is turned off when the indicated value falls below it. However,

by setting the hysteresis, it is turned off when the indicated value falls below the HI limit

further lowered by the hysteresis value.

This function is effective to prevent chattering in such a case where signals fluctuate

(vibrate) subtly.
