For example, 2048 samples can be uploaded to SKF @ptitude Analyst in 45 minutes
from an SKF Multilog WVT on line power. Whatever the data collection schedule setup,
the data viewable in SKF @ptitude Analyst was collected a minimum of 45 minutes ago.
If the trace interval is set as less than the 45 minutes needed to complete the data
upload, DataController will override the invalid value with the default trace interval
value of two hours as shown in the table.
When troubleshooting, you may want to temporarily shorten the interval to collect data
more frequently. For example, with the Trace Interval set to every 15 minutes, you
must reduce the number of samples to 256. This will allow the SKF Multilog WVT to
complete sending the traces for all four channels to SKF @ptitude Analyst within 15
minutes.
WARNING! If the time interval is reduced for testing, battery power will be
consumed more quickly. Be sure to return the device to its regular settings when
you are finished.
WARNING! DataController overrides the invalid value silently. The user-selected
trace interval will still appear in the application as entered. The trace interval
actually being used by the system can be found in the SpectrumCollectNvs file,
discussed in the Wireless Device Manager (WDM) User Interface User Manual,
Chapter 9, SKF Multilog WVT Maintenance.
