Turning On the SPM Diagnostic
The SPM diagnostic is enabled by selecting On for “SPM Mode”, shown on
Figure 7-14. Upon enabling SPM, the diagnostic will automatically begin
“Learning” with the following exception: if valid baseline values have been
previously established and “Monitor” has been selected as the option for
Power Interruption on the Baseline Configuration screen, then the diagnostic
will bypass Learning and begin Monitoring immediately. The diagnostic status
will stay in the Learning mode for the Learning Period specified on the
Baseline Configuration screen. After the learning period is complete, the
Mode will change to Verifying and a blue line will appear on the charts
indicating the learned baseline value. Upon completion of the Verify mode, the
diagnostic will use the parameters selected on the Verification Criteria page to
validate the baseline value. After the Verifying period the Mode will switch to
Monitoring and grey lines that indicate the sensitivity setting will appear on the
charts.
