Safe and widely used: with the measurement category of CAT.II 300 V. The socket tester is guaranteed for one year and is able to protect you. The device is ideal for electrical maintenance testing, testing of office sockets, power strips and sockets in laboratories, factories and homes.
RCD-Pfrüng: After pressing the RCD button for two seconds, the socket tester simulates an earth termination and tests the RCD circuit breaker (residual current device) to determine safe electrical wiring. Recommended are the standard sockets parallel to GFCI sockets. Please use this function carefully with normal sockets to avoid triggering the house wiring
Easy and safe operation: even amateurs can check the voltage, wiring condition quickly and accurately with the socket tester, actively test RCD, discover leakage voltage and leakage current. The easy-to-follow signs save you the time and cost of calling an electrician and provide you peace of mind at all times. The compact size guarantees a handy grip and effortless insertion/unplugging.
Clear and understandable instructions: in German clearly printed display correct connection (RCD current and voltage shown) and present errors (leakage voltage and leakage current shown) are clearly drawn. This makes a quick and accurate detection of wiring errors possible and potential danger can be avoided.
Choking the risk in the bud: the three indicator lights alert you to six potential wiring errors, namely ①Grounding interruption ②Zero interruption ③Phase interruption ④Phase/Earth interrupted ⑤Phase/zero interrupted ⑥Phase/Earth interruption.

Distance-dependent signal – to increase sensitivity of the current tester sensor, hold down 12 V switch button until test probe turns yellow. The light frequency changes depending on the distance from the testing voltage
Detects magnetic fields – the line detector with LED light and pocket clip perceives AC voltages by reacting to electric field strength that builds up around AC voltage conductors
Contactless voltage tester – The P 1032 allows non-contact voltage testing from 12 V to 1000 V AC. Simply hold the device to a socket, lamp holder or an insulated cable
Acoustic and visual signal – if AC voltage is at the measuring point, the integrated LED of the cable finder flashes red. In addition, a beep and a vibration alarm indicate a live line
3-year warranty and information: the phase tester has an on/off switch and can be used for circuits with 50/60 Hz. Safety: EN 61010-1; CAT IV 1000 V. Accessories: batteries and instruction manual3
