Figure A-1: Monitoring Switch Status
When monitoring the status of a switch with your data logger, keep in mind that the logger will
not detect more than one change per sample period. For this reason, use a fast sample rate if
you expect the switch to open and close frequently.
The type of graph produced when monitoring switch status is a square wave that rises to a
maximum value when the switch is closed, and falls to a minimum value when the switch is
open.
