Test Pens

A test pen is a screwdriver-shaped test tool that shows the presence of voltage with a lamp in its handle when its end touches a conductor; it is chosen according to the installation it will be used on (mains or vehicle), the voltage range printed on it, the blade type and the length. The electrical type is used to find the phase terminal in sockets, switches and terminal blocks, and the automotive type to find the points in a vehicle's electrical system that battery voltage reaches. This category includes İzeltaş slotted and Phillips electrical test pens in 135 mm and 190 mm lengths, and an automotive test pen in 135 mm length. A pen made for mains is not used on a vehicle installation, and an automotive pen made for low-voltage vehicle installations is not used at mains voltage. A test pen is not a measuring instrument: it does not show the value of the voltage and is not sufficient on its own to prove the absence of voltage; a multimeter is used for measuring values and a two-pole voltage detector for verifying the absence of voltage.
