This feature allows the user to maintain a list of WITSML values that should be ignored globally by Live. They are applied to every channel, and only to data collected after they are saved.
The values are ignored at the Parser. So, if it is necessary to remove null values in the historical data, it would be necessary to recollect and renormalize.
The WITSML Null Values screen allows to user to maintain the Null Values list. It's located under Configurations > High Frequency Data > WITSML Null Values.
