  • Notes
  • The Radio City Products Co. Inc., New York City made this Multitester model 447A in quite a simple way. It has only a knob for selection of 4 measurements, called "Circuit Selector": DCV/MA, ACV, RX1 and RX100/1 MA plus a zero adjust knob. The selection of different values is done by plugging. The general row is for 100 MA, 10 MA, 1 MA and volts: 5, 50, 250, 500 and 2500, the latter for DC only.
