Check the Mains Voltage with the Multimeter

When renovating, it is often inevitable that lamps or sockets have to be dismantled or moved. It is of vital importance to check whether there is voltage on the lines and connections before loosening the clamp connections. Suitable multimeters do a good job here. However, the user must know exactly what to do.

Measurements in circuits >33V/AC and> 70V/DC may only be carried out by specialists and trained persons who are familiar with the relevant regulations and the resulting dangers.

Note : When it is 230V power, it is an AC voltage. The multimeter must therefore be set to AC voltage. If it is on DC voltage, it will show 0V or only a low value of a few volts, even if the full mains voltage is present. A measurement error that can have fatal consequences.
