Cannot detect cables behind plaster, underground cables, etc. It is also not possible to detect the output of safety transformers with secondary ECT (Earth Centre Tap). This device must be checked for proper function with a known reference voltage before use. Volt-Stick AC display. Sophisticated pocket devices for detecting 50 Hz alternating voltages. These are battery-operated pen-like units with nylon tips that glow red when voltage is detected. No contact or flowing current is required to activate the unit. Ideal for locating breaks in power cables, checking the wiring of plugs, testing fuses, distinguishing between live conductors and neutral conductors, finding live cables in junction boxes, and identifying faulty switches as well as determining the defective lamp in a series circuit.

230 V: Range 220 to 400 Vac (with respect to ground potential). Sensitivity is optimized for detecting mains voltages of 230 V/50 Hz.
110 V: Range 90 to 400 Vac (with respect to ground potential). Sensitivity is optimized for detecting voltages of 110 V/50 Hz, commonly found in factories and other industrial applications.
