SYMBOLS

* INTERNAL CONNECTION

Among Selector Switch settings, this indicates that the valve pin is connected inside the valve to an electrode for the purpose of improving mechanica! rigidty. As the internal connect­ion may be to a different electrode for any given valve type, it is essential that this pin be left unconnected to the valve tester (Selector Switch to 0). lf it is required to know which elect­rode is internally connected to the asterisked pin, this may be done with an ohmmeter on a suff­iciently low range to discriminate between heater resistance and a direct connection.
