A computer implemented machine translation system and method is provided that improves the accuracy of output from one or more machine translation systems by applying one or more data correction routines. A scale plate is provided with graduations corresponding to values of the waveform. The method also includes logging a second temperature value during frosted operation of the evaporator, calculating a difference of the first and second temperature values, and defrosting the evaporator when the difference exceeds a pre-determined value.
