I am guessing that all the nominal resistances are quoted at 70F and that the 500K is 500K ohms. The only one that will work of the four then is 10K OHM NTC THERMISTOR. If you had more choice you would look for one at 5Kohms because the 10Kohms will only measure down to 12C > I guess I will also have to figure out which 680 ohm resistor to get out of > 19 available from the place in TX > http://www.alliedelec.com/search/searchresults.aspx?dsNav=Ntk:Primary%7c680+ohm+series+resistor%7c3%7c,Ny:False,Ro:0&dsDimensionSearch=D:680+ohm+series+resistor,Dxm:All,Dxp:3&SearchType=0&ps=60&fromsearch=true&term=680+ohm+series+resistor Buy cheap ones 1/4 watt or 1/8 watt Resistor; Carbon Film; Res 680 Ohms; Pwr-Rtg 0.25 W; Tol 5%; Axial Tony _______________________________________________ IAEP -- It's An Education Project (not a laptop project!)
