Figure 3-21 Performance Monitoring Alarm Configuration
NOTE:
Keep in mind that these alarms are meant as relative settings and are monitored
with sensors less accurate than those used in calibration instruments. In other
words, assuming the transmitter system has been measured and is compliant in
both respects (SNR and shoulder measurements), and the eCDi™ is showing
alarms, the alarm threshold values should be raised until no further alarms occur.
These alarms are now relative to a known good signal and will give an alarm if
the system degrades.
