Sample Application
A test engineer uses Series 982s to control the temperatures of several
automated test chambers. His computer is linked to the controllers
through its EIA-422 serial communications port. His computer program
monitors the temperatures of the chambers and initiates automatic test
sequences when certain program parameters are met. After completing a
sequence, the computer loads the next temperature profile to the con-
troller. The computer periodically interrogates each controller for its
process temperature, set point and alarm status. This information is
stored on a disk to provide test verification data for the completed prod-
ucts.
