Abstract

329,774. Runbaken, J. H. April 9, 1929. Vacuum tubes. - An electrical testing device comprises a solenoid type voltmeter having an iron core h provided with an indicator b which moves in a slot c in a casing a, a lamp socket d, terminal connections f at the bottom of the casing and a switch m for connecting in circuit a neon lamp e, or an adapter may be inserted in the socket d. The neon tube may be connected in shunt with the voltmeter coil j.
