While at a customer site we were using the Closed Loop Data screen to monitor the Maximum Analog signal. While watching the screen it appeared to be changing and fluctuating incorrectly between a wide range of values for several cycles of the die before coming to a final value.

A code review showed that the values were getting reset during the entire time that the graphics screen was capturing data. It can be capturing data for up to 30 seconds which is why we were seeing it take numerous die cycles before it settled on a value.

The code was modified to only reset the analog and error max values one time at the beginning of a capture so that it would work as expected.
