Pinpointing Cable Faults in “Digiphone” Mode
30
The fault arrow, which can be enabled or disabled through the menu item in the
device settings (see page 25), shows whether the user has moved towards or away
from the fault. This message results from a comparison between the last measured time
difference of the previous position and the current time difference. The fault arrow can
have the following states:
no information
In the previous position a transit time difference and
therefore a comparative value could not be measured
no information
The most recently taken measurement deviates by more
than 10% from the previous measurement and is not
considered for a direction indication
closer to the fault
The last change in position decreased the distance to the
fault
further from the fault
The last change in position increased the distance to the
fault
in close proximity to the fault
The last two readings indicate that the sensor is placed
near the fault position
When pinpointing faults using the fault arrow, you must always move forwards
with the sensor (in the direction of the arrow on the sensor). If the direction
indicator tells you to turn round, you must indeed turn 180° along with the sensor!
