AMS 2750F-Qualified operating temperature range

What's your explanation for the following item?
Let's take an exmaple to clarify if we are on the same page.
One Aging furnace, the norminal setting point temperature is 100℃ - 200℃. The temperature uniformity has been tested which is comply the tolerance is +/-3℃.
Then my question is the qualified temperature range is 100℃ - 200℃ or 97℃ - 203℃?

Thanks very much.

Now I think the qualified temperature range is 100℃-200℃ and the tempereture uniformity is +/-3℃.

Right?
