Important

Trade offs between number of items saved and the controller performance include the following.
- Increasing the number of items saved delays display processing and affects measurement interval.
  Please confirm measurement interval prior to performing set up.
- There is a difference in amount of memory used of approximately 2 MB between 1000 items and 100000 items.
  Please confirm the amount of memory remaining prior to performing set up.
