Share 'The Three Temperature 'non' amigos....'

Something I should imagine that has happened to most of us... I have a Rev2 machine for small trial batches and when it reads one temperature, my digital probe reads another and my surface digital gun reads yet another.....  I suppose I could just chuck the whole lot out but then what would I do. Intuit the temperature. Divine it or just go with the standard lip test.   any Ideas would be welcome…
