DigiPHONE+ NT Datasheet
The Megger DigiPHONE+ NT Pinpointing Receiver Set is a fault locating device capable of acoustic and step voltage fault location featuring an acoustic frequency range of 100 to 1500 Hz and a step voltage sensitivity of 5μV to 200V. Megger DigiPHONE+ NT devices determine precise fault locations while automatically filtering out interfering signals and automatically setting all parameters without technician adjustment. BNR technology is integrated, enhancing acoustic quality and noise immunity by reducing background noise. This set contains 2 pinpointing receivers: the DigiPHONE+ and the ESG SNT. The DigiPHONE+ completes distance measurements in milliseconds or meters/foot and the ESG NT blends high measuring sensitivity with automatic adaptation, detection and adjustment of the device. Together, the two pinpointing detection instruments equip technicians to perform all aspects of cable sheath fault testing.
