ABSTRACT:
A voltage tester, particularly for relatively low voltage A.C., comprises a device having a contact for electrical connection to an electrical component, and a contact that may be touched by an operator through whom capacitive connection may be made to earth. The device includes liquid crystal displays powered by the voltage under test via a voltage multiplier.
