Filter mode setting technique
The T-506 uses a high-performance microprocessor and digital signal processor (DSP) to
process the acquired sound and magnetic field signals in real time and perform continuous
digital filtering operations.
During use, the user can select low pass, band pass, high pass or all pass filter modes
according to the test environment and conditions, in order to get better discharge sound
detection effect. The appropriate filtering mode will filter out noise or interference outside
the passband while receiving the cable fault discharge sound. This improves the signal-to-
noise ratio of the fault discharge sound.
The T-506 can sense a
person’s
touch. When a human hand touches the metal part of the T-
506 handle, the unit will automatically cut off the transmission of the sound signal to avoid
the strong vibration caused by touching the instrument and stops its transmission to the
headphones. When the user removes the hand from the handle, after a period of delay, the
T-506 automatically resumes the transmission of the sound signal.

Installation and adjustment

Battery Connection
Due to airline regulations, the unit is often shipped with the battery disconnected. When the
unit is first unpacked, plug the charger into a suitable power outlet and insert it in to the
charger socket on the detector (section 2.7). Press the on/off button.
If the unit’s Power light
does not illuminate, it is probable that the battery is disconnected.
Remove the handle and turn the Detector over. Look at the underside of the Detector as
below and, using a cross-head screwdriver, remove the 9 screws (position shown by the
orange line) on the bottom of the detector.
Note these screws are quite small, it is recommended that they are kept in a suitable
container to ensure they are not lost.
Lift up the yellow cover of the detector and plug the battery cable in to the socket marked in the
photograph above (right). If the cover is difficult to lift, try to rotate it a little.
