If you see the result is under 400 millivolts, then it shows you with a poor thermopile. Such a device works on the principle of the thermoelectric effect, i.e., generating a voltage when its dissimilar metals (thermocouples) are exposed to a temperature difference. If it reads more than 400 millivolts, then it shows you with a good thermophile output for your device. A thermocouple is a device made of two different metals which creates a small electrical charge when heated at one end by the gas pilot. If you can't light the pilot, the problem most likely lies with the gas control valve or the gas flow itself, not the thermocouple.
