Page 7: Dangers When Working With Electric Voltage
For your safety Dangers when working with electric voltage During measurements with protrac® in combination with a cable fault location system or a surge voltage generator, a dangerous – and sometimes very high – voltage is gen- erated that is fed into the test object via an HV connection cable and can produce a fatal voltage gradient near the fault location. -

Page 14: Before Commissioning
Before commissioning Pairing protrac® system components If an AGP or headphones are subsequently integrated into a protrac® system, so-called pairing must be performed. To do this, the devices are paired with the CU via Blue- tooth® the first time they are used. This procedure need only be performed once, after which the connection is established automatically. -

Page 20: Acoustic Pin-Pointing - Tips, Settings
Tips Evaluation of the acoustic and electromagnetic signals For acoustic pin-pointing using protrac®, the propagation times of the acoustic and electromagnetic signals are compared (coincidence method). This is helpful, for exa- mple, for cables laid in pipes or under concrete: The acoustic signal is often loudest at the end of a pipe or concrete slab, which can be misleading. -
