Function
The comparator output is "ON" (true) if the input is greater
than the reference value or equal to the reference value. If
the input value is less than the reference value, the output
switches "OFF" (false).
The comparator output is "ON" (true) if the input is less
than the reference value. If the input value is greater than
or equal to the reference value, the output switches
"OFF" (false).
The comparator output is "ON" (true) if the input is less
than the reference value or equal to the reference value. If
the input value is greater than the reference value, the out-
put switches "OFF" (false).
There are two reference values. The comparator output is
"ON" (true) if the input is greater than the first reference
value or less than the second reference value. If the input
value is less than the first reference value or equal to the
first reference value or greater than the second reference
value or equal to the second reference value, the output
switches "OFF" (wrong).
There are two reference values. The comparator output is
"ON" (true) if the input is greater than or equal to the first
reference value and less than or equal to the second refer-
ence value. If the input value is less than the first reference
value or greater than the second reference value, the out-
put switches "OFF" (false).
