The PKI 4300 is used to check telephone lines, AC networks, alarm circuits and also LAN cabling. In the process, the telephone and line detector checks used and unused cables for capacitive and inductive tapping as well as metrological abnormalities. Analog or digital modulation can be detected to ensure that no audio signal is transmitted via the checked telephone and/or network lines. With the pulse localisation method, the distance from the measuring point to the tapping point can be determined.

PKI 4300 is portable and therefore ideally suited to be used quickly, effectively, accurately and safely. The instrument is operated via a single rotary encoder (jog dial) and an intuitive user interface. The large and bright color touchscreen greatly improves ease of use and helps you work quickly and accurately. The built-in lithium-ion battery provides six hours of operation. PKI 4300 can also be used in mains operation via the supplied smart charger. The rugged and stable housing allows it to be used in challenging environments and adverse conditions. Using so-called delta U-trigger technology, the best trigger timing is always automatically hit. The Linux-based operating system provides the highest level of reliability and cyber security.
