What is a CAT-2 meter?

I am understanding you to be asking about the division or category in relation to the power supply category 2 being from the panel and toward the interior, cat 3 is for the area outside pole and meter socket fluke has a small diagram that breakes these areas down rather well. if you do maintainance and deal with a wide range of electrical ( hopefully all within your licensing and abilities)there are several nice selections would recommend ( go to basic test or the digital meters under the products list
(dont know how to post a direct link or i would) can anyone explaine that please?
