If you prefer to use a refrigerant manifold, mQ supports bluetooth capable manifolds from JB, Yellow Jacket, Fieldpiece (such as the SMAN series), and Testo. Like the wireless probes, the manifold needs to be "Mapped" in the Toolbox screen of the Toolbox. The measurements from the manifold are actually separated and need to be assigned. It is somewhat confusing in that when mapped properly, it will appear as if they're mapped twice. Don't believe me? Check out the pictures below of Fieldpiece and Testo manifold mapping. JB and Yellow Jacket are identical, I just had these handy.
