Monitoring
At the data acquisition rate of 5 minutes, the SEL-2414 stores at least 10 days of
all analog signals selected for profiling in nonvolatile memory. The report
includes the time of acquisitions and the magnitude of each selected analog
quantity. By defining conditions in the signal profiling enable SEL
OGIC variable
setting (SPEN), you can record analog values only at particular periods or condi-
tions of interest. Depending on the card configuration of the device, you can
choose any analog quantity shown in Appendix I: Analog Quantities.
Because the data are optimally formatted for machine-to-machine compatibility,
use software such as Microsoft Excel to display the profile data. Figure 5.29
shows the data and graphed data after importing the data (comma-delimited) into
an Excel spreadsheet. Use the PRO C(lear) command to clear all profile data.
