ISD SENSOR OUT
System Setup Self-Test
ISD MONITORING CATEGORY
System Self-Test Monitoring algorithms are designed to ensure the proper setup and operation of the ISD monitor.
Among other items, the self-test algorithms will check for a properly configured TLS Console monitor as well as the
correct number of functioning sensors and interface modules.
System Self-Test Monitoring algorithms are broken down into two types of tests:
1. ISD sensor out self-test, designed to monitor for properly functioning sensors.
2. Setup self-test, designed to verify the monitor configuration.
DIAGNOSTIC PROCEDURE
Verify that the ISD setup is complete.
