AMS terms
Resistance: This is the existing resistance reading of the thermocouple loop.
Resistance threshold exceeded: The check box indicates if the sensor resistance has passed the Trigger
Level.
Trigger level: Threshold resistance value for the thermocouple loop. The trigger level may be set for 2, 3,
or 4  Baseline or the default of 5000 Ohms. If the resistance of the thermocouple loop surpasses the
Trigger Level, a maintenance alert will be generated.
Baseline resistance: The resistance of the thermocouple loop obtained after installation, or after
resetting the baseline value. The trigger level may be calculated from the baseline value.
Reset baseline resistance: Launches a method to recalculate the Baseline value (which may take several
seconds).
TC diagnostic mode sensor 1or 2: This field will read either enabled or disabled indicating when the
thermocouple degradation diagnostic is on or off for that sensor.
LOI
Reference the Figure 2-21 to find the path to the thermocouple diagnostic in the LOI menu.
