What is the advantage of using a reference grade triple axis meter?
A. It is far more accurate due to the fact that it measures fields in all 3 dimensions as opposed to only one at a time. For instance, you may have a high reading in the x direction and a low one in the y direction. If you only happen to pay attention to one axis, then you are not getting the true reading and may either miss an issue, or be misled into thinking there is one.
