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.
