Outputting the Comparator’s Results
There are two ways to determine the state of the comparator. The LEDs of the Comparator Panel,
and the optically isolated, open collector outputs of the Control I/O Connector on the rear of the
instrument.
Comparator values may be entered and sorted into BINs 1~9. When a measured value falls within
ant of the ranges of BINs 1~9, the TOTAL-GO LED will light. When a measured value falls outside
of the defined 1~9 BIN ranges, then either the “LO” or “HI” LEDs on the Comparator Panel will
illuminate (depending on whether the measured value is higher or lower than the BIN settings).
Measured values outside of the comparator range will be sorted to BIN 0.
For instructions regarding the pin connections of the Control I/O Connector, refer to “Programming
and Interfacing”
