Issue Details

This document provides additional information regarding the function of the Real Time Clock battery on the sbRIO-9607 used in the MON-10496. 

Solution

The primary function of the Real Time Clock (RTC) battery is to allow the sbRIO to continue keeping accurate time when power is not provided to the sbRIO. When power is removed from the sbRIO the RTC battery will be drained. If this battery were to die the RTC would no longer be keeping accurate time and this would be reflected by incorrect timestamps on collected data. The sbRIO 9607 User Manual provides recommendations for increasing the battery life of the RTC battery.

Because the MON-10496 interfaces with InsightCM it has an additional measure in place to ensure accurate timestamps. The InsightCM server has its own sense of time so that the timestamps can be adjusted after the server has connected to the MON-10496.

If for some reason you believe your battery is dead or you are seeing incorrect timestamps on your data please reach out to National Instruments.
