-Easiest way to do this is to disconnect the thermistor and measure voltage between both pins. With no thermistor connected, it should be full supply voltage, 3.3\_or 5\_volts depending on the controller.+Easiest way to do this is to disconnect the thermistor and measure voltage between both pins on the board.

-This measurement is simple, too. Disconnect the thermistor and measure resistance between both pins. At room temperature this should be around the nominal value of the thermistor, typically 10\_kOhms or 100\_kOhms. Warming the thermistor by hand should reduce this resistance.+This measurement is simple, too. Unplug the thermistor connector and measure resistance between both pins there. At room temperature this should be around the nominal value of the thermistor, typically 10\_kOhms or 100\_kOhms. Warming the thermistor by hand should reduce this resistance by a few kOhms.
  
 Measuring the thermistor while it's plugged in gives false results. Measuring the thermistor while it's plugged in gives false results.
