You can press MODE key (as an ESCAPE key) to

IMPORTANT : The Lo SET + ½ Lo HYS should be less
than Hi SET - ½ Hi HYS i.e. Hi SET and Lo SET value (in
consideration of the hysteresis band) can never overlap. Lo
HYS and Hi HYS can be set independent of each other; this
allows non-symmetrical hysteresis option.

NOTE : The maximum
value of Hysteresis is
4% of its Full Scale (FS)
selected. The Lo HYS
hysteresis is spread
equally on either side of
the Lo SET point.
