Wait again with
the deviation low
limit alarm
Alarm when the deviation (measured
value-set value) is greater than the alarm
set value, but the measured value will be
ignored when the power is turned on and
the set value changes

Wait again with
the
deviation
high/low
limit
alarm
When the absolute value of deviation (|
measured value - set value |) is larger
than the alarm setting value, the
measured value will be ignored when the
power is switched on and the set value
changes
± input width

Input scope
：
The value between the lower input value and the upper input value. For example,
if the upper and lower limits are 100 and 1000 respectively, the range is 101
～
999.
2.Input width
：
Width from the lower limit to the upper limit of the input value (upper limit-lower limit). For
example, if the upper limit is 100 and lower limits is 1000, then "+ input width" is "0
～
900" and "± input
width" is "
－
900
～
900"
