Maybe even a large styrofoam cup or thermos bottle (steel coffee mug?) and a coil-type immersion heater. Or maybe a plastic coffee pot thing. Anyway, just boil some water. Dunk the probe in the boiling water. Read the gauge on the instrument panel. You should be able to get enough slack on the probe wire to just unscrew it from the engine and drop it into the boiling water. I will say that I have not tried this myself yet. However, this technique tests the entire system (probe plus electronics). Note that a small correction may be needed for higher altitude airports. I don't know the boiling point of water at altitudes other than sea level. - Rob Wolf >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> LML website: http://www.olsusa.com/Users/Mkaye/maillist.html LML Builders' Bookstore: http://www.buildersbooks.com/lancair Please send your photos and drawings to marvkaye@olsusa.com. >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
