Curator Response: Thanks for the report. Three positional adjustments do not include temperature adjustment, and temperature compensation (via an expansion balance) is not the same as being adjusted to temperature. This particular grade may very well be adjusted to temperature, but no grade descriptions have been found to date that support temperature adjustment.
