  1. Malfunctions can be diagnosed using infrared thermography without affecting the work state of tested equipments, thus the diagnostic accuracy can be improved. infrared thermography, just as often, improves electronic fault diagnosis by isolating the malfunction to specific areas of the circuit board, what is more, it usually does point directly to the failing component. thermography even can rapidly diagnose up to hundreds of elements on one pcb at one time, without requiring the operator to know the circuit principle very well, which can reduce the workload greatly

    紅外故障檢測儀可以對電子設備進行在線測量，檢測時不會影響待測設備的正常工作和頻率特性，這對高頻電路的檢測尤其方便，且能提高診斷的準確性;他通常能指出電路板上的故障區域，甚至經常能直接找出故障元器件，這樣就提高了維修質量;並且能在不需要檢測人員對電路原理有深入理解和分析的情況下，對同一塊電路板上的數十隻甚至數百隻器件同時進行快速診斷，這就大大減少了維修人員的工作量，提高了維修人員的工作效率。
