4.1 Comparator Function
42
The comparator function compares measured values to preset upper and lower
thresholds, judges the measurements according to their relative levels within the
preset range, and indicates the results of the comparisons.
Comparator thresholds can be set either by specifying upper and lower thresh-
olds, or by specifying a reference value and tolerance.
Comparator results can be indicated by the Hi, IN and Lo LEDs, beeper sound
and signal output at the EXT I/O connector.
See "Chapter 5 External Control (EXT I/O)" (p.79).
The comparator setting process flow is as follows:
