Thermal resistance short-circuit and cut-off solution

Under normal circumstances, the process of using thermal resistance is relatively smooth, but occasionally, there will be a failure occurs, the two common should be short circuit and open circuit, the circuit is largely about because of heat resistance of the wire is too thin, the thermal resistance under it and below small make up together to get to know the cause of the short circuit and open circuit and the solution.

in fact short circuit and open circuit is easy to distinguish, need to use multimeter, using a multimeter to test, if test value is less than the R0, basic it is short, but if the measured values shows the infinity, that is basic circuit, between the two, the short circuit of the solution is simple, in does not affect the thermal resistance wire, find the location of the short circuit will blow dry it, and the insulation strengthening is ok; If is open circuit, when solving the necessary changes to the length of the thermal resistance of four, so the effective way of resistance is to be replaced, if need to use the welding way of processing, so need to check after welding. And if the display instrument of thermal resistance, according to the value than the actual value of the value of low or display has not been stable, so even if is to protect pipe internal appears smudgy, only need to remove protection tube internal dirt can be, and shows the value of the negative, under normal circumstances are thermal resistance in the connection error, or a short circuit in heat resistance, direct connection mode change.
