Question by PF: Electrical testers look like screwdrivers but have no instructions/precautions. How are they used safely?
Some types have pictures showing a finger being used to complete the circuit e,g, when testing fuses.
But how can you test whether there is a current going through a live socket with just a single screwdriver-shaped tester & how is the result shown if it doesn’t have an LED or digital display?
