By accident I just lowered my new torque wrench 1-2 mm below the minimum torque setting without using it. does it mean it is now uncalibrated?
Welcome to the forum.
Assuming this is a rotation micrometer style torque wrench.
If the wrench is rotated past the minimum by a small amount, but not so far that the handle unscrews from the mechanism threads, then it is fine.
When doing that on my wrenches I am laser focused on that activity to ensure that problem doesn’t occur
More information. In fact, even if you did a little something wrong, the tool can still be fine. You can contact a specialist, test it at work.
