A Vintage Voltage Tester from Czechoslovakia (Vadaska)
In this video I introduce to you a vintage voltage tester also called "Vadaska" made in Czechoslovakia. The version ZN1 I have in the video was made in 1981. The device is possible to use for testing the mains voltage, for measuring voltage and for testing 3-phase motors. In the video I show you how to use it for testing the mains voltage and for measuring voltage.
