a reverse polarity protection diode and a PNP power control transistor. Power Off While displaying the result of the last test a long key press powers the tester off. The tester will show a good bye message and then power off. As long as you press the key the tester stays powered on....
That integrated diode junction creates a parasitic transistor. A NPN BJT will have a parasitic PNP and vice versa. If such a BJT is found the tester shows a '+' behind the BJT type. TRIAC TRIACs can be used in three or four different operation modes, also known as quadrants. Usually ...
