Questions & Answers

Does this meter have a magnetic back?

Does this meter have a magnetic back?
Asked by: Lester
Klein offers 2 magnetic hangers that work with a variety of their meters. From my research, neither of them fit the CL 312. Would like to know for sure from Klein, because I'm considering a Cl312 myself.
