If it is necessary to perform maintenance functions such as changing system
parameters, performing tests, or changing the mode of operation, the operator can
press one of three menu buttons to bring up one of the three system menus. The
resulting menus will be different for the Control Module and the Signal Conditioning
Card. The Control Module user interface will be explained first since this is the
primary system operation point. The Signal Conditioning Card user interface would
normally only be used in diagnostic or troubleshooting activities.
