5.1 Comparator Measurement Function
Function
Description
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
results can be indicated by the Hi, IN and Lo LEDs, beeper
sound and signal output at the EXT I/O connector.
❖ For details about comparator signal outputs at the EXT I/O connector,
refer to Chapter 6 External Control (Page 77).
