I just bought a new 0-7000 rpm  Teleflex tach for my old tracker from e-bay.  I will not have any problem installing and hooking it up, but the gauge came with no instructions., so I'm very concerned about the Calibrate setting on the back of the gauge.  All input would be appreciated.

Here is a link to the Teleflex Marine site with the downloadable manuals in PDF format. Would have given a direct link but their was no model number mention in your post.
