(5) Relation between the comparator outputs and hysteresis width and behaviors of comparator status lamps.
HH comparator (or HI1 comparator)
When the measured value exceeds the HH
compared value, the HH comparator output
is turned ON and [HH] lamp lights up in red.
When the measured value lowers the (HH
compared value - hysteresis width), the HH
comparator output is turned OFF and [HH]
lamp lights up in gray.
HI comparator (or LO1 comparator)
When the measured value exceeds the HI
compared value, the HI comparator output is
turned ON and [HI] lamp lights up in red.
When the measured value lowers the (HI
compared value - hysteresis width), the HI
comparator output is turned OFF and [HI]
lamp lights up in gray.
LO comparator (or HI2 comparator)
When the measured value lowers the LO
compared value, the LO comparator output is
turned ON and [LO] lamp lights up in
yellow.
When the measured value exceeds the (LO
compared value + hysteresis width), the LO
comparator output is turned OFF and [LO]
lamp lights up in gray.
LL comparator (or LO2 comparator)
When the measured value lowers the LL
compared value, the LL comparator output is
turned ON and [LL] lamp lights up in red.
When the measured value exceeds the (LL
compared value + hysteresis width), the LL
comparator output is turned OFF and [LL]
lamp lights up in gray.
OK comparator
The OK comparator output is turned ON and
[OK] lamp lights up in white when all [HH],
[HI], [LO], and [LL] outputs are OFF (the
measured value is between the LO compared
value and HI compared value).
