A capacitor is connected in series with OUTPUT terminal with capacitor 0.047 μF/400 V. It is very convenient to use this terminal when the operator needs to measure AC signal element alone in T V or audio circuit where DC and AC elements are mixed. DC element is blocked by the capacitor.

Then depending on the polarity of the transistor to be tested, insert the probe jack into the black lead if it is NPN transistor and into the red lead if it is PNP transistor. There are two lead lines each with an alligator clip at the end. Connect the black clip to the base terminal of the transistor and the red clip to the collector terminal.
