Even in a very noisy environment, Model-139B still can determine quickly and precisely the positive and negative polarity of a loudspeaker、headphone、receiver, and every single unit in a loudspeaker system. Model-139B also includes 3 sets of external input terminals and selectors which can be used to combine with other instruments, to measure the other features of a loudspeaker simultaneously.
