Note For Thermistors Measuring 1K Or Less At Operating Temperature

If your thermistor measures less than 1k at operating temperature, our cunning temperature monitoring circuit will run into difficulties and keep on cutting out. This problem can be easily avoided with these thermistors by placing an ordinary 560R resistor in series with the thermistor.

Simply measure the combined resistance of the thermistor/resistor combo when doing the above.
